摘要: Abstract The air side performances of two louvered fin surfaces under dehumidifying conditions were examined in this study. test results indicated that the effect pitch on heat transfer performance is comparatively small, and friction factors increase significantly with for fully wet conditions. inlet relative humidity sensible negligible. However, there a detectable condition type (I) louver due to condensate retention. A correlation heat, momentum, mass was proposed correlate present database mean deviation 5.94%, 6.1%, 7.89%, respectively.
