摘要: AbstractThe influence of air speed, spray density and tube bundle on wet cooling the fins are analyzed through numerical solution. The water droplets released from surface injection source in discrete phase model (DPM). And film is formed three-dimensional using Eulerian wall (EWF). species transport coupled with EWF to solve transition heat exchange. exchange pressure loss evaluated field synergy principle Fanning friction factor, a comprehensive performance factor obtained. Based outer diameter 57 mm, 50 mm 42 mm, mass transfer coefficient 57 mm higher than that other two under varied flow rate density. Besides, increase rows number weakens unit area. When Re exceeds 2,820, finned more become...
