对于液滴在固体表面上冷凝或蒸发的情况，通过求解半无限大固体上球形液滴的稳态热传导方程，分析了固体材料性质和液滴接触角对液滴在固体表面上冷凝或蒸发的影响。在获得该解决方案时，假设热量仅通过液滴传递到固体或从固体传递，并且在固液界面处存在完美的热接触。在适当的边界条件，在液-气界面的一些精确的和近似的解决方案，然后被用来获得通过液滴的总热流。
For droplets condensing on or evaporating from a solid surface, the effects of the solid material properties and the droplet contact angle are analyzed by solving the steady heat-conduction equation for a geometry consisting of a spherical segment droplet on a semi-infinite solid. In obtaining the solution it is assumed that heat is transported to or from the solid only through the droplet and that there is perfect thermal contact at the solid-liquid interface. With suitable boundary conditions at the liquid-vapor interface some exact and approximate solutions are found and then used to obtain the overall heat flow through the droplet.
