NUMERICAL INVESTIGATION OF COOLING MECHANISM OF LAMINATE POROUS PLATES
This paper deals with fundamental research on heat transfer and cooling effectiveness. The cooling configuration adopted in this study integrates impingement cooling and pin cooling devices into one body. The target plate is provided with several discharge holes with inclination angle of 60 degree. The focus of this study is influence of blowing ratios on the cooling effectiveness and heat transfer on the target plate. Coupled fluid/solid heat transfer calculation was performed to obtain the temperature distributions, the complex flow and heat transfer patterns in the laminate plate using the commercial codes FLUEN6.1. The result showed that the flow in the impingement holes and the film holes was asymmetry. The heat transfer coefficients were non-uniform on the target plate. The influence of blowing ratios on the impingement cooling and film cooling were analyzed to understand the effect on the cooling effectiveness of lamilloy. Heat quantity percentage of different region was analyzed on detail.
