通过在径向坐标系中求解组分守恒方程、动量守恒方程和能量守恒方程，建立了气相环境中液滴蒸发的新解析模型。该模型消除了以往简化模型的一些不一致之处，并给出了非等温情况下的解。研究了不同蒸发流体在等温和非等温稳态条件下的流场特性。对非定常液滴蒸发过程进行了预测，并与现有的简化麦克斯韦方程和著名的Stefan-Fuchs模型进行了比较。
A new analytical model of liquid drop evaporation in gaseous environment is developed based on the solution of species, momentum and energy conservation equations in a radial coordinate system. The model relieves some inconsistencies of previous simplified models and it yields solutions also for the non-isothermal case. The flow field characteristics under isothermal and non-isothermal steady-state conditions are investigated for different evaporating fluids. The unsteady drop evaporation process is predicted and comparison with the existing simplified Maxwell equation and the well known Stefan–Fuchs model is reported and discussed.
