ABSTRACT
Pioneering work by D. A. Nield and A. V. Kuznetsov modeled the heat transfer and fluid flow in bi-disperse porous medium (BDPM). Assuming local thermal equilibrium within the microporous media, a volume-averaged two-velocity two-temperature model was proposed to simulate steady-state fluid flow and heat transfer in BDPM. Porous medium channel flows have found several engineering applications. In a subsequent work, Arunn Narasimhan et al. modeled heat-generating electronics as BDPM and studied forced convection cooling as a function of micro and macroscale porosities and permeabilities of the medium. The BDPM channel was considered as a two-dimensional porous block array, and in turn made of arrays of regularly arranged square electronic components distributed uniformly. Fluid flow through the micro and macropores of the BDPM channel was visualized as removing the heat generated by the electronics components. Bi-dispersion effects may also be induced by varying the macropore volume fraction and number of blocks in the BDPM channel.
