双液滴撞击平面液膜的流动与传热特性
The flow and heat transfer characteristics of double droplets impacting on flat liquid film
摘要
Abstract
A coupled level set and volume of fluid (CLS-VOF) method is applied to simulate the process of double droplets which continuously impact on a hot liquid film on a wall of constant temperature, and the evolution processes after the double droplets impinge on the hot flat liquid film are studied. Influences of vertical spacing between the two droplets, impact velocity, film thickness and droplet diameter on the flow and heat transfer characteristics are discussed. It is found that the average heat flux density of the wall increases with the rise of impact velocity. The influences of vertical spacing between the two droplets, droplet diameter, and liquid film thickness on the average heat flux density are small, but they have an important effect on the distribution of heat flow density in the impact area and the border area.关键词
