Local endwall heat/mass-transfer distributions in pin fin channels Academic Article uri icon

abstract

  • Naphthalene sublimination experiments were conducted to study the effects of the pin configuration, the pin length-to-diameter ratio, and the entrance length on local endwall heat/mass transfer in a channel with short pin fins (pin length-to-diameter ratios of 0.5 and 1.0). The detailed distributions of the local endwall heat/mass-transfer coefficient 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 3.3 × 104. Overall- and row-averaged Nusselt numbers compared very well with those from previous heat-transfer studies. © American Institute of Aeronautics and Astronautics, Inc., 1987, All rights reserved.
