Effect of Tip Clearance on the Thermal and Hydrodynamic Performance of a Shrouded Pin Fin Array

摘要

In this paper the authors present the experimental results of the effects of tip clearance on the thermal and hydrodynamic performance of a shrouded pin fin array. The authors have employed the most modern experimental techniques to obtain their result's. This is indeed an excellent experimental work. The authors refer to two cases of existing similar experimental work, where pin fins have been used for cooling purposes: (a) cooling of turbine's blades in aircraft engines and (b) cooling of electronic equipment. A comprehensive discussion with regard of turbines' experiments, it can be found in the recent book by Han et al.. On the other hand, the authors' work can be useful to manufacturers that produce ready made electronic coolers found in the market as CF-512, BF-02, etc.
