Résumé :

Lluvias extremas se han observado en el norte del Perú, el impacto de estas lluvias sobre la infraestructura presente en las ciudades es importante, esto debido a la alta vulnerabilidad de la zona. Los eventos ocurren principalmente en verano. Por lo tanto, se han seleccionado catorce casos de lluvia extrema, las que se registraron durante diciembre y marzo del 2001 y 2002. En la presente investigación se realiza una evaluación de la simulación numérica de lluvias en el norte del Perú. Se empleo un modelo regional atmosférico llamado RAMS (Regional Atmosphere Modeling System) el cual ha sido implementado en la zona norte del Perú usando la técnica de anidamiento para reducir la resolución. La evaluación de la simulación de lluvias es realizada midiendo la correlación entre las lluvias registradas y las simuladas por el modelo RAMS. Los resultados muestran una mayor correlación para la cuenca alta, un valor intermedio de correlación para la cuenca media, y los menores valores de correlación se observa en la zona baja de la cuenca. Estos valores para la cuenca alta, media y baja son: 0.49, 0.44, y 0.15 respectivamente. Aunque estos valores son aparentemente bajos, se ha presentado valores de correlación de 0.90 para la cuenca baja de la cuenca, al simular todo el evento de lluvia extrema. También valores de correlación de 0.94 fue observada en la parte alta de la cuenca. Se mencionan algunas explicaciones de los bajos valores de correlación, así como algunas medidas de mejora en los sistemas de adquisición de datos.

Résumé :

En este trabajo se considera la propuesta, desarrollo y simulación numérica de un sistema que modela el comportamiento del tratamiento del VIH-1, utilizando antirretrovirales. El sistema definido para tres variables dependientes de la variable t, denotadas por X(t)= (x1(t), x2(t), x3(t)) representan a la cantidad de Linfocitos T "Helpers" (CD4), cantidad de Linfocitos T Citotóxicos (CD8) y Carga Viral del proceso de infección del VIH-1 en cualquier instante de tiempo t, respectivamente. El sistema conformado por un conjunto de Ecuaciones Diferenciales Ordinarias No lineales, cuyo dominio existencial del sistema representa el tiempo de evaluación del proceso de infección y eliminación del virus en un paciente con VIH-1. Este conjunto de estados del Sistema Dinámico No lineal, asociado a las condiciones de valor inicial es denominado Problema de Cauchy. Existen pocos estudios relacionados a la solución de este sistema, de los encontrados algunos se reducen al estudio en dos variables y otros sin la obtención de la solución explícita.

La equivalencia está basada en el Teorema de Grobman – Hartman y se encuentra la solución explícita mediante el método de Runge Kutta de 4to orden. De este modo se obtienen los resultados del modelo y cuya convergencia, está garantizada por la consistencia y estabilidad del esquema numérico. Palabras clave.- Tratamiento antirretroviral, Modelamiento matemático VIH, Sistema dinámico no lineal, Método de Runge Kutta de cuarto orden.

Résumé :

The article was created on the grounds of numerical modelling of shaped charges with a focus on the unconventional shape of their liners. The standard shaped charge of the “deep penetrating” type is equipped with a conical liner made of copper. Three various geometries of shaped charges featuring unconventional shape have been modelled and compared with the classical model of a shaped charge. The shaped charges have been compared for maximum pressure during detonation, cumulative jet velocity, kinetic energy gained and length of cumulative jet after 22 µs. The purpose of modelling shaped charges, featuring unconventionally formed liners, was to check whether they are able to improve the perforation job parameters in oil and gas wells. Perforation of the borehole is a critical job, enabling the initiation of hydrocarbons production from a specific reservoir. The job consists in making series of channels perpendicular to the borehole axis, penetrating casing walls, the cement layer and the formation rock, in order to create a hydraulic link between the borehole and the reservoir of hydrocarbons. In the oil industry, the “deep penetrating” type shaped charges are designed in order to provide optimal length of the perforation channel, while maintaining its adequate perforating diameter. Nowadays, the most commonly deep-penetrating shaped charges used, are the axially-symmetric shaped charges with conical liners made of copper powders. The charges create a cumulative jet reaching a velocity of approx. 7000 m/sec and are able to penetrate up to 1 m of rock matrix in favourable conditions. The article describes the parameters of shaped charges, that have been obtained as a result of numerical modelling. In order to finally confirm the target penetrating ability by the modelled shaped charges, one should check their real physical models in fire-ground conditions.

Résumé :

Las ondas enfocadas, fenómeno que ocurre en el océano, es responsable del fallo de estructuras localizadas costa afuera. Existen pocos trabajos enfocados a su estudio en zonas cercanas a la costa. En el presente trabajo se estudió la estabilidad y funcionalidad de un dique vertical con banqueta baja en presencia de ondas enfocadas. Para ello, se realizaron ensayos en un canal de oleaje. Mediciones de superficie libre, presiones, subpresiones, y rebase fueron utilizadas para validar un modelo numérico que resuelve las ecuaciones RANS. Las predicciones de rebase y presiones/subpresiones máximas del modelo numérico presentaron diferencias promedio con respecto a las mediciones de 10% y 8%, respectivamente. Posteriormente, el modelo numérico se utilizó para evaluar el papel de la posición relativa de la estructura. Finalmente, se compararon los resultados del modelo físico con formulaciones semi-empíricas, encontrando diferencias significativas en rebase (≈100%) y en presiones y subpresiones (88%). Este estudio demuestra que el uso de modelos tipo RANS es una alternativa a las clásicas formulaciones semi-empíricas, pues se comparan mejor con las mediciones durante este tipo de fenómenos.

Résumé :

Various delineation methods, ranging from simple analytical solutions to complex numerical models, have been applied for wellhead protection area (WHPA) delineation. Numerical modeling is usually regarded as the most reliable method, but the uncertainty of input parameters has always been an obstacle. This study aims at examining the results from different WHPA delineation methods and addressing the delineation uncertainty of numerical modeling due to the uncertainty from input parameters. A comparison and uncertainty analysis were performed at two pumping sites—a single well and a wellfield consisting of eight wells in an unconfined coastal aquifer in Israel. By appointing numerical modeling as the reference method, a comparison between different methods showed that a semi-analytical method best fits the reference WHPA, and that analytical solutions produced overestimated WHPAs in unconfined aquifers as regional groundwater flow characteristics were neglected. The results from single well and wellfield indicated that interferences between wells are important for WHPA delineation, and thus, that only semi-analytical and numerical modelling are recommended for WHPA delineation at wellfields. Stochastic modeling was employed to analyze the uncertainty of numerical method, and the probabilistic distribution of WHPAs, rather a deterministic protection area, was generated with considering the uncertain input hydrogeological parameters.

Résumé :

The results of numerical modeling in longitudinal ventilated sloping road tunnels are given. The slope of the tunnels varies in the range of 0-6%. The geometry of the tunnel is as follows: length: 100 m; width: 8 m; height: 6 m; area of the seat of fire: 16 m2. The seat of fire sized: 2.75x5.8x1.5 m is in the central part of the tunnel. The scenarios of development of 5, 10, 20, 30, 50 MW fires are studied in the case of positive and negative directional ventilation flows. The time of modelling was 120 seconds. The numerical problems were modelled with a volumetric grid method. The grid cell dimensions were: 0.5*0.5*0.5 m. Virtual point and volumetric measuring equipment was used to record the modeling results. The modelling used 4 groups of measuring devices that measured and recorded air velocity, temperature, and air and smoke densities. The paper discusses cases of algebraically summarizing the ventilation and fire-induced flows. Based on the results of numerical modeling, we can point out that the widely accepted indices of critical velocity and back-layering length in inclined road tunnels often give erroneous results. Therefore, in strategies for emergency ventilation, indicators such are critical velocity and back-separation should be used with caution.

Résumé :

Abstract Online coupled meteorology–atmospheric chemistry models have greatly evolved in recent years. Although mainly developed by the air quality modeling community, these integrated models are also of interest for numerical weather prediction and climate modeling, as they can consider both the effects of meteorology on air quality and the potentially important effects of atmospheric composition on weather. This paper summarizes the main conclusions from the “Symposium on Coupled Chemistry–Meteorology/Climate Modelling: Status and Relevance for Numerical Weather Prediction, Air Quality and Climate Research,” which was initiated by the European COST Action ES1004 “European Framework for Online Integrated Air Quality and Meteorology Modelling (EuMetChem).” It offers a brief review of the current status of online coupled meteorology and atmospheric chemistry modeling and a survey of processes relevant to the interactions between atmospheric physics, dynamics, and composition. In addition, it highlights scientific issues and emerging challenges that require proper consideration to improve the reliability and usability of these models for three main application areas: air quality, meteorology (including weather prediction), and climate modeling. It presents a synthesis of scientific progress in the form of answers to nine key questions, and provides recommendations for future research directions and priorities in the development, application, and evaluation of online coupled models.

Résumé :

This paper presents some experimental results of a bullet impact on composite armor together with numerical modeling approaches. The development of light composite sandwiches for ballistic protection is the target of a project in terms of which the research is being conducted. Traditionally, a vehicle ballistic protection is mainly achieved through metal-based armor which is extremely heavy, hence the increasing popularity of composite sandwiches. Numerical simulations allow for a reduction of the number of experiments needed to obtain appropriate design of ballistic protection, but they require verified modeling approaches and proper material data. Therefore, different modelling approaches for both parts of the composite sandwich have been tested and possibilities to adjust these models to experimental data were investigated.

Résumé :

Sensitive clays are known for producing retrogressive landslides, also called spread or flowslides. The key characteristics associated with the occurrence of these landslides on a sensitive clay slope must be assessed, and the potential retrogressive distance must be evaluated. Common risk analysis methods include empirical methods for estimating the distance of potential retrogression, analytical limit equilibrium methods, numerical modelling methods using the strength reduction technique, and the integration of a progressive failure mechanism into numerical methods. Methods developed for zoning purposes in Norway and Quebec provide conservative results in most cases, even if they don’t cover the worst cases scenario. A flowslide can be partially analysed using analytical limit equilibrium methods and numerical methods having strength reduction factor tools. Numerical modelling of progressive failure mechanisms using numerical methods can define the critical parameters of spread-type landslides, such as critical unloading and the retrogression distance of the failure. Continuous improvements to the large-deformation numerical modeling approach allow its application to all types of sensitive clay landslides.
