Interaction of a dispersed liquid flow with a heated surface

Abstract

A study is made of certain features of the interaction of a flow of dispersed liquid with a heated surface in the dry regime and under conditions attending a transition to the wet regime.The interaction of a dispersed liquid with a heated surface plays an important role in many areas of technology, particularly rocketry, cryogenics, heat treatment of materials, nuclear reactor engineering, etc.It has been established experimentally [i, 2] that this process may take place in different regimes: in one regime, there is direct contact between the liquid droplet and heated surface; in another, the interaction occurs through a vapor interlayer.The regime in which the interaction takes place determines such important characteristics of the interaction process as the rate of heat exchange between the heated surface and liquid.
