Abstract:

For reasons of environmental compatibility and sustainability, the demand for more efficient heat exchangers is growing. The design of heat exchangers is based on experimentally determined correlations. For the use of heat exchangers under flow conditions that have not been researched yet, complex experimental investigations are necessary or a safety factor is applied. A third alternative is the investigation using Computational Fluid Dynamics (CFD). For this, however, it is necessary to generate an exact numerical model. Therefore, this study deals with the generation of a numerical model to simulate a condensation process of a widely used natural refrigerant, namely ammonia, within a plate heat exchanger (PHE). Based on the results of the pressure drop and the heat flow, the simulation’s plausibility is checked with a validation test case. Thus, a statement about the accuracy of the CFD simulation is given.
