Validation and sensitivity analysis of the mathematical model of a cross - flow heat exchanger with non - uniform flow of agents

The paper deals with experimental and numerical thermodynamic analysis of a cross-flow heat exchanger with non-uniform flow of mediums through the exchanger. The main aim of the work is validation of a computer code for analyses of the considered type exchangers. The validation procedure was realized by means of comparison of the experimental and numerical results. Next, the sensitivity analysis of the code was also accomplished. Selected results of analyses carried out and the most important conclusions are presented in the paper.
