Abstract This work presents a two-phase flow model for compressible fluids coupled with heat transport simulation. The coupling is realized via equations of state, which are used to determine the relation between temperature, pressure and density of a fluid. The density correlation is necessary to describe the compressibity of a gas or a liquid, furthermore, density together with temperature affects fluid viscosity and thermal conductivity. Using the coupled H(2)T-model, we developed a test scenario based on an enhanced gas recovery application. This test case consists of a 1D cutout from a natural gas reservoir in the vicinity of the CO(2) injection well. The simulation shows the displacement of natural gas by carbon dioxide at the first stage of injection. A simplified simulation with constant fluid properties but similar conditions was compared to an analytical solution to prove the validity of the governing equations.
