Numerical Study on Splash Conditions of an Integrated Droplet-type Divertor

A level set method combined with the second-order RKCN projection method for the multiphase incompressible flow was developed and applied to a free surface flow divertor concept. Crank-Nicholson method for the diffusion term was used to eliminate the numerical viscous stability restriction. The high order ENO scheme was used for the convective term to guarantee the accuracy of the method. The results show the numerical methodology is successful in modeling the hydrodynamics of the multiphase flow even if severe surface deformation occurs. Through performing the different conditions of the droplets like size, velocity, inject angle, we give a detail description on the splash conditions of the integrated droplet-type divertor
