Numerical Modelling Of Transport In Complex Porous Media: Metal Foams To The Human Lung, Christopher T. Degroot
Numerical Modelling Of Transport In Complex Porous Media: Metal Foams To The Human Lung, Christopher T. Degroot
Electronic Thesis and Dissertation Repository
Transport in porous media has many practical applications in science and engineering. This work focuses on the development of numerical methods for analyzing porous media flows and uses two major applications, metal foams and the human lung, to demonstrate the capabilities of the methods. Both of these systems involve complex pore geometries and typically involve porous domains of complex shape. Such geometric complexities make the characterization of the relevant effective properties of the porous medium as well as the solution of the governing equations in conjugate fluid-porous domains challenging. In porous domains, there are typically too many individual pores to …

Study Of Vocs Transport And Storage In Porous Media And Assemblies, Jing Xu
Mechanical and Aerospace Engineering - Dissertations
Indoor VOCs concentrations are influenced greatly by the transport and storage of VOCs in building and furnishing materials, majority of which belong to porous media. The transport and storage ability of a porous media for a given VOC can be characterized by its diffusion coefficient and partition coefficient, respectively, and such data are currently lacking. Besides, environmental conditions are another important factor that affects the VOCs emission. The main purposes of this dissertation are: (1) validate the similarity hypothesis between the transport of water vapor and VOCs in porous materials, and help build a database of VOC transport and storage …
