Thermal instability in a porous medium with random vibrations

Onset of thermal convection in a layer of saturated porous medium, heated from below, is examined when the layer is subjected to random vibrations. It is shown that when the vibrations are characterized by a white noise process, they hasten the onset of convection. Further, decrease in permeability tends to stabilize the flow field.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41712/1/707_2005_Article_BF01175814.pd
