Abstract:

ABSTRACT The most important aspect of the ongoing research project is to develop numerical coupled hydraulic-structural analysis models of oil containment booms. This should be later applicable for investigation of the efficiency limits of a new system of oil spill containment booms called Cavalli system. This system consists of surrounding the oil slick with a special boom and protecting it against waves and currents. It provides the possibility to divide the encircled area in several smaller circles and to increase the thickness of the oil slick inside. The whole system consists of a two-pha

Abstract:

The squeeze oil-film dampers have been applied to damp out vibration in linear guideway systems of CNC machine tools. An accurate estimate of squeeze oil-film damping effects is significant to predict the dynamic performance of rolling guidance systems. This paper presents a finite element method to solve the fluid-structure interaction problem of squeeze oil-film dampers. Three-node Mindlin plate element is used in the structure domain model. The oil-film behavior is provided by the Reynolds equation of lubrication theory. Both the structural domain and fluid domains are discretized by finite

Oil, gas condensates, oil products present a complex colloidal-dispersed system which often demonstrates the abnormally changing properties when external conditions change. Mixing the petroleum products can be accompanied by a non-linear behavior accompanied by synergistic and antagonistic effects. Understanding of the oil and oil products as oil dispersed systems, the specific features of intermolecular interaction largely clarify their behavior, changes in properties, chemistry and mechanism of reactions occurring in them. Petroleum systems are polydisperse, in which the components can coexi

Abstract Specialized glands that produce and store floral oil are found in 11 families of flowering plants, with greater representation in Malpighiaceae.

Summary Understanding proppant-transport and -deposition patterns in a hydraulic fracture is vital for effective and economical production of petroleum hydrocarbons. In this research, a numerical-modeling approach, combining the discrete-element method (DEM) with single-/multiphase lattice Boltzmann (LB) simulation, was adopted to advance understanding of the interaction between reservoir depletion, proppant-particle compaction, and single-/multiphase flows in a hydraulic fracture. DEM was used to simulate effective-stress increase and the resultant proppant-particle movement and rearrangement

Abstract:

Slug multiphase flow is known to be the most prevalent regime because of its extensive encounters associated with chaotic behaviour, complexity and instability that cause significant fluctuations in operating conditions and thus lead to undesirable effects. In this study, the effect of varying crude oil grades on slug characteristics is numerically investigated. A partitioned one-way coupling framework of fluid–structure interaction (FSI) one-way coupling framework is adopted to investigate the influence of changing oil grades and slug characteristics on the maximum induced stresses in horizon

Abstract The absorption of liquid into a pore network structure depends on porosity, pore size distribution, surface free energy of the involved phases, and external pressure. In the case of ink setting on coated paper, significant decrease of accessible pore volume can take place due to swelling of latex binder particles when contacted with the vehicle of oil-based ink. The reduction in pore network connectivity can be detected by an optical retlectance measurement procedure based on the refractive index differences between the coating components and the surrounding medium present in the inte

The toxicity of 32 shale oil components to a mixed marine bacterial culture and the mode of toxic joint action in mixtures of the components was assessed. The great bulk of shale oil (alkanes and alkenes) was of very low toxicity. The Pyridlnes were the most hazardous group of compounds tested. Based on differences in chemical structure It was not possible to predict the mode of joint action between compounds. The form of interaction in mixtures was both additive and synerglstlc. Thus the addition of the toxicity of Individual components of shale oil would greatly underestimate the oil's true
