WebCOMBUSTION IN POROUS MEDIA: FUNDAMENTALS AND APPLICATIONS. A.A. MOHAMAD, in Transport Phenomena in Porous Media III, 2005 Abstract. Porous medium is a good candidate for enhancing the combustion efficiency and reducing pollution formation, such as soot, CO and NO x.It is possible to obtain a super adiabatic … WebWe compute effective properties (i.e., permeability, hydraulic tortuosity, and diffusive tortuosity) of three different digital porous media samples, including in-line array of uniform shapes, staggered-array of squares, and randomly distributed squares. The permeability and hydraulic tortuosity are computed by solving a set of rescaled Stokes equations …
WebDec 6, 2012 · In the mid-seventies, a new area of research has emerged in subsurface hydrology, namely sto chastic modeling of flow and transport. This development has been motivated by the recognition of the ubiquitous presence of heterogeneities in natural formations and of their effect upon transport and flow, on the one hand, and by the vast … WebThis is simply too idealistic a model for performance assessment of flow and transport through a partially saturated, fractured porous formation. Natural fractures are characterized by rough surfaces. In fractures at depth under compressional stress, the walls are pressed together, with a finite fraction of fracture surfaces in contact, such ...
Weblaminar flow through porous media. Assuming the flow governed by Darcy’s law, we look for a relation between mean drift and random component of the velocity. This introduces … WebSep 27, 2003 · [1] Flow and transport of nonreactive solutes in heterogeneous porous media is studied by adopting a multi-indicator model of permeability structure. The porous formation is modeled as a collection of blocks of uniform permeability K implanted at random in a matrix of constant conductivity K 0.The multi-indicator model leads to simple …
WebAug 31, 1998 · The transport and reaction of fluids in porous media results in unique pore growth and channel evolution as the media are dissolved. This often leads to the formation of highly conductive flow channels, commonly referred to as wormholes. The objective of this work is to predict the influence of transport and reaction on the structure of the …
