采用数值计算的方法，以水为流动介质，研究了圆管内插入螺旋片状多孔介质在充分发展的层流区的换热及流动综合性能，并与环状和圆柱状多孔介质插入物进行了对比，此外，利用场物理量协同原理对计算结果进行了分析。结果表明，在圆管内插入螺旋片状多孔介质可以有效提高换热与流动的综合性能，其PEC达到3．60—3．95．“,”The present study introduced a tube inserted with helical screw-tape porous media which can make the fully developed laminar flow in the tube to form an equivalent thermal boundary layer, and thereby enhance the heat transfer between the fluid and the tub
