abstract
Naphthalene sublimation experiments were conducted to study the effects of the pin configuration, the pin length-to-diameter ratio, and the entrance length on the local endwall heat/mass transfer in a channel with short pin fins (pin length-to-diameter ratios of 0. 5 and 1. 0). Experimental data were obtained for staggered and aligned arrays of pin fins, for the spanwise pin spacing-to-diameter ratio of 2. 5, and for streamwise pin spacing-to-diameter ratios of 1. 25 and 2. 5. The Reynolds numbers were kept at about 33,000. Data on the effect of the Reynolds number on the local channel endwall heat/mass transfer from a previous study were included for comparison.
