A few numerical algorithms for a solution to the non-stationary heat transfer equations in terms “temperature — heat flow vector” are discussed. In other words, non-stationary problem in the mixed formulation is considered, and spatial approximation is implemented by the Mixed Finite Element Method. For the vector equation of the mesh heat flow a few splitting schemes are analyzed. Main attention is given to the comparison of an accuracy of the proposed schemes.
Keywords: splitting scheme, mixed finite element method, heat transfer, approximation, stability.
