Conventional wisdom for NMR interpretations of water-saturated porous media is that the NMR spectra are analogous to the pore size distribution of the system. This is the basis for understanding porous media as containing large vs. small pores, and is used as a justification for NMR-based permeability correlations. However, there are cases whereby issues of poor connectivity between pores can s...

Free convection effects and heat transfer due to a pulsating point heat source embedded in an infinite, fluid saturated, porous dusty medium are studied analytically. Both velocity and temperature fields are discussed in the form of series expansions in the Rayleigh number, for both the fluid and particle phases based on the mean heat generation rate from source and on the permeability of the p...

The Problem of convective flow in fluid saturated porous medium has been the subject of several resent papers. Interest in understanding the convective transport processes in porous material is increasing owing to the development of geothermal energy technology, high performance insulation for building and cold storage, renewed interest in the energy efficient drying processes and many other ar...
