Numerical and experimental study of the hydrodynamics of a heat exchanger

The work provides a comparative analysis of the results of numerical modeling and experimental studies of fluid flow in a heat exchanger (HE). The OpenFOAM package for solving CFD problems was used as a tool for numerical modeling. Experimental studies were carried out on the TMJ-2M hydraulic stand. The heat exchanger was connected directly to the modules of the hydraulic stand. Distilled water at room temperature was used as the working fluid. Verification of the experimental results was carried out on the basis of numerical modeling in the OpenFOAM package using the same characteristics of the media used in the field experiment. Analysis of the obtained data showed good convergence of the results of the numerical and experimental study of the multi-section HE.
