Comparison of calculation of cooling systems in the two-dimensional COLD program and the three-dimensional Ansys program

The basis of this work was an analysis of the advantages and disadvantages of the COLD software package, designed for two-dimensional models, and the ANSYS software package, which allows solving both two-dimensional and three-dimensional problems. Based on the calculation results, it was concluded that the ANSYS software package, which takes into account a larger number of parameters, unlike COLD, has the most accurate calculation results, since the calculation model in the three-dimensional program is closer to the physical model.
