The numeric investigations of a high temperature compact gas/gas heat exchanger are shown in this paper. The results of the numeric modelling and their analysis for two different simulation models with and without the regards of the development of the velocity field are presented in the article. The results have been obtained for two different geometries one of which is the two semi-channels model and second of which regards the heat transfer through the heat exchanger volume. The article presents the comparison of the model solutions with the evaluation of the received reliability results. The comparison between the simulations and experimental results are presented too. On the base of the second numeric model the two-dimensional simulation task with the regard of the inlet and outlet volume before and after the heat exchanger was developed. The influence of the change of the channel sizes on the hydraulic and thermal characteristics of the researched heat exchanger is shown. The solution of this two dimensional model confirms the inhomogeneous distribution of the hydraulic and thermal fields in the heat exchanger. The obtained results were analyzed with the conclusions and further investigations complete the represented results. “COMSOL-Multiphysics” was used for the numeric simulation.
