A Diffuse Interface Model for the Numerical Simulation of Thermocapillary Effects

The aim of this paper is to present a simple diffuse interface model for compressible two-phase flows with thermo-capillary effects. We mainly focus on two aspects; the continuum formulation of thermo-capillary forces, and the influence of the model used for the computation of the transport coefficients in the interfacial region. Several validation test cases of increasing complexity are considered for the assessment of the model.Copyright © 2009 by ASME
