Abstract

The paper considers an approach to the modeling of geometric and finite element models of complex shaped shell-and-tube heat exchangers intended for space thermal power plants. The approach allows the construction of high-quality finite element meshes necessary to achieve calculation errors in the region of values close to 5 %. It also demonstrates a comparison of the results of calculations with the results of an experiment on stretching the tube sheet of a heat exchanger with a set of 37 tubes. The results of geometric and finite element modeling presented in the article were obtained using the domestic CAE Fidesys software package.

Keywords:

shell-and-tube heat exchanger, tube plate, fidesys, calculation, experiment
