热边界层的厚度与距离布风板的位置关系不大。
The thickness of thermal boundary layer has little relations with the distance away from the air distribution.
结果表明，可调节的流场和边界层的厚度，可降低与多孔介质的热传递，因此可以提高在管道中。
The results show that the flow field can be adjusted and the thickness of boundary layer can be decreased with the porous medium so the heat transfer can be enhanced in the pipe.
