| Abstract: | Experiments were performed,in which the heat-mass transfer analogy and thenaphthalene sublimation technique were employed,to investigate the heat trsansfer and flowresistance of elliptic pin-fin plate in crossflow of air.The effects of pin-fin arrangements andReynolds number are also discussed.The experimental results show that the staggered pin-finplate has greater mean Nusselt number and Euler number compared with the in-line pin-finplate. |
