NUMERICAL SIMULATION OF 3D HEAT CONDUCTION PROBLEMS WITH PHASE TRANSITIONS USING AN HPC CLUSTER
The article describes the iterative algorithm for solution of conjugate heat conduction problems with phase transitions. The phase transition boundary is determined by using explicit method (accurate to a control volume), the temperature field in every phase is computed by implicit method. The control volume method in the Cartesian coordinate system and the enthalpy method were used. The algorithm is implemented in software for numerical solution of freezing-thawing problem in layered heterogeneous media. The software is parallelized using MPI standard. Tests were carried out and demonstrated the agreement between results, analytical solutions and numerical solutions obtained by other researchers.
