...Han Yan; Lei Luo; Junfeng Zhang; Wei Du; Dan Huang; Songtao Wang Purpose This paper aims to investigate the influences of dimple location on the heat transfer performance of a pin fin-dimpled channel with upright/curved/inclined pin fins under stationary and rotating conditions. Design...

...Lei Luo; Yifeng Zhang; Chenglong Wang; Songtao Wang; Bengt Ake Sunden Purpose The pin fin is applied into a Lamilloy cooling structure which is broadly used in the leading edge region of the modern gas turbine vane. The purpose of this paper is to investigate effects of the layout, diameter...

...Mustafa Turkyilmazoglu Purpose This paper aims to present an elegant exact solution in terms of elementary functions for a special pin fin without the classical length-of-arc approximation. Design/methodology/approach The temperature distribution along the fin and the surface function, both...

...Lei Luo; Wei Du; Songtao Wang; Weilong Wu; Xinghong Zhang Purpose The purpose of this paper is to investigate the optimal geometry parameters in a dimple/protrusion-pin finned channel with high thermal performance. Design/methodology/approach The BSL turbulence model is used to calculate...
