Direct Numerical Simulations of Multiphase Flows

Three dimensional numerical simulation on bubble growth and merger in microchannel boiling flow

“…The volume expansion produced by the phase change on the interface is computed by the right hand term, in which _ q refers to the heat flux flowing into the interface. It is computed by adding up the heat fluxes on both sides of the interface [25]:…”

“…ðr l þr v Þh 3 ps q for the surface tension[25]. A CFL number of 0.1 was given, thus it should satisfy Dt 0.1 h/u max , where u max is the maximum velocity.…”

A three-dimensional volume of fluid & level set (VOSET) method for incompressible two-phase flow

“…We applied projection method [11] for solving the pressure and velocity fields. A second-order Runge-Kutta method is used for time advancement.…”

Numerical simulation of high Schmidt number flow over a droplet by using moving unstructured mesh
