摘要
Reported are the results of experiments on a regular in-line-jet that was modified prior to its impingement to improve heat transfer on the plate. Modifications consisted of insertion of two bluff bodies and a streamlined body in the jet. The improvement in transport coefficients was attributed to the periodicity in the flow which caused the attachment point to sweep the reattachment region and the turbulence created was distributed over a large area compared to simple attachment.
