一种模拟液体雾化的守恒型Level Set方法

A Mass Conserving Level Set Method for Simulation of Liquid Atomization

本文发展了一种追踪气液界面的守恒型Level Set(LS)方法。针对LS方法本身质量不守恒的缺陷,本文提出了基于局部曲率的质量弥补修正措施,提高了LS方法的质量守恒性。本文采用Zalesak's disk和二维变形速度场两个验证性算例验证了该方法的准确性。该方法为以后详细研究雾化机理奠定了坚实的基础。

A mass conserving level set（LS） method is developed to capture the gas-liquid interface.The lost mass is remedied by considering the local interface curvature.The Zalesak＇s disk and two dimensional deformation velocity field are used to demonstrate the accuracy of the present method.This method lays a solid foundation for further investigation of mechanism of liquid atomization.
