Sprzężenie przepływu cieplno-dyfuzyjnego w ujęciu numerycznym

The paper is gone on the scientific research which apply to phase transition in the thermodiffusion processes. They proceed under the influence of action external agents. There was presented results of phase transition solid body to liquid body. The process is described by the system equations, which allow for mutually coupled heat and diffusion flows. The numerical solution of these equations were obtained by finite difference method of numerical analysis. The computer program was written Visual C++. The program enables the simulation of the mutually process for different boundary and initial conditions and changeable source, which generate transitions. Moreover there was made an analysis of convergence of applied computational method.
