采用平行板上冷凝传热传质同时进行的气相和冷凝层厚度控制方程，对平行板通道内的混合对流换热进行了计算研究。允许入口压力在0.5 bar至1.0 bar之间变化。其他参数，如热Grashof数（Gr（t））、浮力比（B-r）、雷诺数（Re）、Jakob数（Ja）、通道长度（LW）在462至1.92 × 10（4）、0.228至1.93、26至2000、0.0156至0.047、37.5至75之间变化。给出了显热Nusselt数和凝结Nusselt数的局部变化规律，并将诱导速度、压降、总显热Nusselt数和总凝结Nusselt数与控制参数进行了关联。(C)2015年Elsevier Masson SAS。All rights reserved.
A computational study is made on mixed convective heat transfer from a parallel plate channel using governing equation for both gas phase and condensate layer thickness under simultaneous heat and mass transfer representing condensation on a parallel plate. Inlet pressure is allowed to vary from 0.5 bar to 1.0 bar. Other parameters, like, thermal Grashof number (Gr(t)), buoyancy ratio (B-r), Reynolds number (Re), Jakob number (Ja), channel length (LW) are varied from 462 to 1.92 x 10(4), 0.228 to 1.93, 26 to 2000, 0.0156 to 0.047, 37.5 to 75. Local variation of sensible heat Nusselt number and condensation Nusselt number are presented and induced velocity, pressure drop, overall sensible heat Nusselt number, overall condensing Nusselt number are correlated with the governing parameters.
