| Abstract: | This paper deals with three different fin-and-tube air coolers in turbogenerators.A set of experimental tests were proceeded to investigate the characteristics of heat transfer and resistance.Based on the experimental study,air-side heat transfer and resistance characteristics of the coolers were developed.Meanwhile,the effects of air velocity,water velocity and the fin space of heat transfer and resistance characteristics were obtained.The research results provided the reference for designing and reforming gas coolers in turbogenerators. |
