...Nihad Dukhan Momentum transport in porous media exists in numerous engineering and process applications, e.g., ground water pollution, storage of nuclear waste, heat exchangers, and chemical reactors. In many of such applications, the porous medium is confined by solid boundaries. These impermeable...

... applications including pipes and micro- and minichannels. However, the approach can also be applied to two phase flow in porous media, fractured media, microgravity, and with proper attention, liquid-liquid applications. It has been 60 years since the publication of Lockhart and Martinelli’s ( 1 ) seminal...

...S.-M. Kim; S. M. Ghiaasiaan The laminar pulsating flow through porous media was numerically studied. Two-dimensional flows in systems composed of a number of unit cells of generic porous structures were simulated using a computational fluid mechanics tool, with sinusoidal variations in flow...

...A. Nakayama; F.
