Full textEn l’actualitat, l’agricultura és l’activitat humana que requereix més quantitat d’aigua. Davant la importància i escassetat d’aquest recurs, l’ús eficient de l’aigua s’ha convertit en una prioritat. D’una banda i si és possible, es fa necessària la utilització de sistemes de reg com el reg per degoteig que empren de forma més eficient l’aigua. D’altra banda, la reutilització d’aigües residuals tractades per l’ús agrícola ajuda a disposar de l’aigua necessària per a reg al mateix temps que permet alliberar aigües de major qualitat per a altres usos. En aquest sentit, el reg per degoteig és el sistema més segur per aplicar aigües regenerades. No obstant això, el seu principal problema és l’obturació dels degoters, que pot afectar negativament al rendiment dels cultius i al maneig de la instal·lació. Per intentar evitar les obturacions, resulta imprescindible instal·lar filtres. Els que millor funcionen amb aquest tipus d’aigües són els filtres de sorra, encara que, degut a la pressió que requereixen, concentren la major part de demanda d’energia dels sistemes de reg per degoteig. En la present tesi es determina l’efecte de tres tipus de filtres de sorra amb diferents dissenys de drenatge (de braços col·lectors, de crepines inserides i de medi porós), l’alçada del medi filtrant (0.2 i 0.3 m) i la velocitat de filtració (30 i 60 m/h) en la qualitat de l’aigua filtrada, la caiguda de pressió en els filtres, el consum energètic del sistema i l’obturació dels degoters

Full textThe filter floor is an essential component in the operation of rapid gravity filters used in drinking water production or wastewater treatment plants. Its main role is to collect and distribute fluids uniformly to optimize the filter in terms of water yield. Despite the importance of this component, experimental and numerical studies on the subject are rare in the literature. Single-phase and two-phase flows inside the filter floor during the filtration and filter backwashing phases, as well as the impact of the floor on the rapid gravity filtration process, have been little studied. In this context, the aim of this study is to collect experimental data on the flows inside the underdrain to determine the most suitable numerical fluid simulation models for optimizing its operation. The development of a test bench on a semi-industrial scale made it possible to experimentally obtain mean velocity fields using 2D2C PIV measurements (Particle Image Velocimetry 2D2C), as well as mean pressure differential measurements in different areas of the floor. A second test facility was set up to characterize the filter media used in the main test rig. The experimental data was then compared with the results of URANS (Unsteady Reynolds Averaged Navier Stokes) and RANS (Reynolds Averaged Navier Stokes) numerical simulations in order to define the turbulence model best suited to the filter's operating mode. These simulations also enabled us to gain a better understanding of the influence of the filtering floor on the flow inside the filter medium and to identify areas for optimization. Void fraction measurements were carried out inside the underdrain for different backwashing rate ratios between water and air, using a tip-type optical probe. These measurements, together with visual observations of the flows during air-only backwashing and simultaneous air and water backwashing, will be used to determine the most suitable two-phase simulation method

Full textThe thesis “Icon & Reality: Cartoon as an essential element in paint layers” deals with the problem of preparatory work in paint layers. It should emphasize on strong experimental nature of research, which is mainly focused on practical and pedagogical application. The thesis is based on the idea of developing and analyzing the old Flemish painting technique, nowadays abandoned, but in a natural and necessary way it flowed until got focused on one of its specific aspects, the apparent lack of technique’s capacity for corrections, while the image is pictorially constructed. Therefore, the key question that summarizes the thesis is: Relevant changes are or are not possible in an image while this is pictorially constructed by an indirect method, as might be the Flemish. The initial work to study the subject interweaves with other similar spiritual subject – Byzantine painting – an artistic form with regular practice in large parts of Europe still today. By comparing both working ways, circumstantial aspects tend to fade and then is easier to get clear and understand the essence of the image constructed by addition of paint layers. The author creates, search and collects a generous number of examples in both mentioned above pictorial techniques. The examples are extended in two more types of paintings, one using third painting technique also imbued with similar problems, and another getting focused in exclusively drawings’ aspects. Of all the experimental material, a number of conclusions regarding the preparatory, general and procedural implementation work are extracted in the following summary. The ecstasy of the creative work should be experienced through preparatory drawings. That is, the climax of the painting must be developed on the cartoon reminding the consequent pictorial work in the strict support as a drawing’s programmed and directed task. No suspense or unknown activity must be in the specifically painting work. Any correction in painting of the original projected drawn image should be considered as something precarious, as a tare. The preliminary drawing or cartoon should be detailed to the max, and, be transferred accurately in its complexity to the ultimate format.
La tesis “Icono y Realidad: El Cartón como elemento esencial a la pintura por capas” versa sobre la problemática preparatoria de la pintura por capas determinante. Cabe destacar del trabajo de investigación su marcado carácter experimental, orientado sobre todo a la aplicación práctica y pedagógica. La tesis, partiendo en un principio de la idea de desarrollar a la práctica una técnica pictórica en desuso hoy, como es la Flamenca, acaba centrándose de manera natural y necesaria en uno de sus aspectos concretos; su hipotética falta de capacidad aparente para obrar correcciones mientras se construye el cuerpo pictórico. La pregunta clave que resume la Tesis sería la siguiente: ¿Son posibles las alteraciones relevantes de la imagen que se construya utilizando a una metodología pictórica indirecta, como podría ser la Flamenca? El trabajo inicial sujeto a estudio se imbrica con otra de talante semejante, la pintura Bizantina, cuya praxis regular aún pervive en amplias zonas de Europa. El motivo es conseguir —mediante la comparación— borrar lo circunstancial y llegar a la esencia de las imágenes construidas por adicción de estratos pictóricos. El propio autor realiza y recoge testimonio documental de una generosa cantidad de ejemplos en las dos técnicas pictóricas ya mencionadas. Ejemplos que se extienden en dos tipologías mas; unos elaborados desde una tercera técnica pictórica imbuida de problemática similar, y otros centrándose exclusivamente en los aspectos de dibujo. De todo el material experimental se extrae una serie de conclusiones respecto al trabajo preparatorio, genéricas y de aplicación procesual que en resumen son las siguientes: 1- En el dibujo preparatorio debe experimentarse el extasis creativo de la futura obra. Es decir, el nudo de la obra se desarrolla sobre el carton; siendo el consiguiente trabajo pictorico en el soporte último una actividad dirigida y programada desde el primero, sin suspense ni incognitas. 2- Cualquier corrección de la imagen original de la pieza pictorica por capas se deberá considerar como algo precario, como una tara. 3- El dibujo preliminar o cartón debe estar detallado al máximo, y ser traspasado al formato último de manera precisa y preciosista, so pena de perder todo lo estudiado en el primero.
