What is F211 Heat transfer and flow characteristics around a porous rectangular cylinder about?

Unsteady twQdimensional numerical study has been done for the forced convection around the porous rectangular cylinder wbich has heat generation . Ifaspect ratio of the porous rectangular cylinder is relatively small , 月ow entering from the f め nt of the cylinder flows out from the rear ofthe cyhnder and suppresses the generation of the Karman vortices . reduces tlle pressure drop behlnd the cylinder . Here the drag coefficient is smaller than that of impermeable solid cylinder . When aspect ratio is relatively large , the pe eating 恥 w drains from the side befbre it reaches the rear and the pressure drop of the wake is not suppressed . Here the drag coefficient may be larger than that of solid cylinder because the internal friction becomes dominant. Heat transfer characteristic aro し md the porous cylinder is strongly affected by the permeating flow, Key nVords : PorQus media , FQrced convection , Flow pat し em , Drag coefficient
