2.
Tile thickness of a liquid microlayer underneath a vapor bubble on a heated, cylindrical probe was determined by simultaneously solving the fourth-order differential equation for the microlayer thickness that incorporates the momentum and energy equations in the microlayer in conjunction with the pressure distribution in the mircrolayer and the evaporative heat flux at the interface.

补充资料：降液管清液层高度
分子式：
CAS号：
性质：又称降液管清液层高度。板式塔降液管内的液柱液面到下层塔板的垂直距离。如图中的Hd（图暂缺）。为保持板式塔正常操作，避免发生液泛，降液管液柱高度不能超过一定限度。一般应满足Hd≤(0.4～0.6)(HT+hw)，式中HT为塔板间距，hw为堰高，系数一般取0.5，易起泡物系取0.4，不易起泡物系取0.6。
