Taschenbuch. Condizione: Neu. Neuware -Two phase flow of gas and oil through a porous medium was simulated by Free Energy model of Lattice Boltzmann Method. Constant pressure boundary condition for Free Energy model was derived and then, capillary pressure curve was determined for high density ratio flow (gas and oil flow) through porous media . A validation test was carried out to calculate pore size distribution from determined capillary pressure curve. Good agreement between this pore size distribution and real pore size distribution of porous medium was seen. Finally, the effect of interfacial tension and contact angle on shape of capillary pressure curve was investigated. Comparison of these results with experimental results of literature in this field shows good consistency between trends of capillary pressure curves. The results confirm that Free Energy lattice Boltzmann method is capable of determining acceptable capillary pressure curve for gas and oil fl ow in porous media which is supposedly the first usage of Free Energy model for this objective.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2013 in the subject Engineering - Computer Engineering, grade: none, University of Wuppertal, course: Computational Mechanics of Engineering - Computational Fluid Dynamics, language: English, abstract: The objective of this thesis is to develop a generic CFD solver to simulate multicomponent gas transport involving multiscales. A comparative study between the mixture and Eulerian approach for multicomponent flows is done. Eulerian approach where every component has its own characteristic velocity is used in this work with reasons stated. Inter-component momentum exchange term has been modelled using Maxwell-Stefan relations. A semi-heuristic drag term for modelling porous drag is used. Temperature transport for the mixture is developed by considering an ensemble averaging method of all components for the mixture. Volume averaged form for all the equations is applied by considering fluid in presence of porous media as a pseudo-homogeneous medium. All the equations and terms mentioned are implemented in the solver. An open source CFD software OpenFOAM has been used to develop the solver. Capability of the solver to simulate diffusion dominated mass transfer has been established by using a Loschmidt tube which involves diffusion of a ternary mixture. Accuracy of 0.5% is observed for the case in comparison with analytical solution for the problem in one dimension. Validation of porous drag and energy transport has been done by using a fully developed laminar flow over two parallel plates and comparing the Nusselt numbers. The Nusselt numbers of 8.85 and 9.13 for porous and non-porous zones were observed compared to the literature values of 7.54 and 9.8. The reason for the deviations are stated.
