Abstract

In the corrugated plate dryer, there are a lot of phenomena of multi-droplets impacting on the liquid film. Therefore, the analysis of droplets successively impacting on liquid film has important engineering significance. In this paper, the CLSVOF method is used to simulate the successive impact of two droplets on the liquid film. By analyzing the velocity and pressure distribution of the liquid film and the motion state of the residual film, the influence of the droplets spacing, the initial liquid film thickness and the impact velocity on the impact outcomes is obtained, and the influence mechanism is analyzed. The simulation results show that the inner crown is easy to splash with the increase of the droplets spacing; with the increase of impact velocity, the inner crown is easy to splash；with the increase of the initial liquid film thickness, the inner crown is not easy to splash.

用 CLSVOF 方法研究冲击参数对液滴连续冲击液膜的影响

在波纹板干燥机中，存在着许多多液滴冲击液膜的现象。因此，分析液滴对液膜的连续影响具有重要的工程意义。本文采用CLSVOF方法模拟了两个液滴对液膜的连续冲击。通过分析液膜的速度和压力分布以及残余膜的运动状态，得到液滴间距、初始液膜厚度和冲击速度对冲击结果的影响，并分析其影响机理。仿真结果表明，随着液滴间距的增大，内冠容易发生飞溅；随着冲击速度的增加，内冠容易飞溅；随着初始液膜厚度的增加，内冠不易飞溅。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
