Abstract In this paper a ppT-formulation for non-isothermal multi-phase flow is given including diffusion and latent heat effects. Temperature and pressure dependencies of governing parameters are considered, in particular surface tension variation on phase interfaces along with temperature changes. A weak formulation of the governing equations is obtained by applying Galerkin's method of weighted residuals. The numerical model is implemented in the framework of the open source scientific software OpenGeoSys based on object-oriented programming (OOP) principles allowing model applications in various geotechnical areas. The classic benchmark for two-phase flow by McWhorter and Sunada(1) is used as a reference case on which non-isothermal effects and non-linear material behavior are studied.
