Abstract: Direct numerical simulation was performed for the heat transfer of airflow in the entrance region of a channel with repeated rib protrusions. The ribpitch to ribheight ratio (Pi/H) was increased from 2.0 to 16.0 by four ...

Abstract: A direct numerical simulation is made for the incompressible turbulent flow in the 180 deg curved channel with a long straight portion connected to its exit port. An examination is made for how the organized coherent ...
