摘要:The governing equations for heat and mass transfer of evaporating meniscus are derived and solved by fourth-order Runge-Kutta method. The equation for evaporating heat flux is originally derived in thermal resistance form and it is found that the key factors that affect the heat transfer of intrinsic meniscus are surface tension and conduction thermal resistance of the liquid film; the suppressing effects of disjoining pressure and surface tension are very strong. The disjoining pressure predominates in extremely thin films while the evaporation driving effect of temperature difference between the wall and vapor is dominant in relatively thicker films. Other factors such as groove width, superheat, surface tension coefficient, latent heat of evaporation, kinetic viscosity and acceleration are analyzed as well. For acceleration, Bond number is introduced to evaluate its influence on the heat transfer of evaporating meniscus.
