多孔質物体まわりの強制対流(一般セッション 対流熱伝達 I)
詳細
A numerical study has been made on forced convection around a porous obstacle concentrating on the effect due to the permeable surface condition. The effects of porous parameter induce a significant change in flow patterns and suppress the Karman vortex in a wake region. Further it is noted that the drag coefficient of a porous obstacle is reduced compared with that of an impermeable object. The degree of the decrease in the drag coefficient of the porous obstacle depends on its permeability and blockage ratio.
