Abstract

Using the methods of self-similarity for a laminar free-convective film boiling on a vertical finite-length surface submerged into a large volume of an arbitrarily subcooled liquid, we have derived expressions for the Nusselt criterion with a continuous transition from the film boiling in the saturated liquid to conditions of the strongly subcooled liquid for heat transfer between the heating surface and the interface, as well as for heat transfer from this interface to the bulk of the liquid while simultaneously taking radiative heat transfer into account. The existence of a hierarchy of different types of self-similarity in the given problem is demonstrated.

大量液体浸没在垂直表面上的层流膜沸腾问题中的自相似性

摘要

使用自相似方法对在垂直有限长度表面上沸腾的层流自由对流薄膜进行沸腾，该平面被淹没到大量的任意过冷液体中，我们推导了Nusselt准则的表达式，其中从沸腾薄膜的沸腾连续转变将饱和液体置于强过冷液体的条件下，以在加热表面和界面之间进行热传递，以及从该界面向大部分液体进行热传递，同时还要考虑辐射热传递。证明了给定问题中存在不同类型的自相似性的层次结构。
