Advection with constant velocity is here added to conduction and phase change. Analytical solution are proposed from Kurylyk et al. 2014 paper based on a reassessment of solutions by Lunardini. Although not physically realistic (constant velocity) these solutions can be used for benchmarking purposes: “Lack of fidelity to physical processes does not limit ability to serve as benchmark”.

The paper Kurylyk et al. 2014 describes at depth the analytical solutions available, the suggested benchmark cases and SUTRA code runs to compare with these solutions. The recommanded benchmark 2 and 3 are included in the InterFrost project as TH1 cases (differing by flow velocities). The recommanded benchmark 1 (Neuman case) is an option to complement the Lunardini case provided as T1.
