Boundary Conditions and Constraint Equations for Simulation of Energy Exchange

摘要

The contribution and presented work deals with the CFD simulation of heating and air conditioning process of a special vehicle. The aim of the work is then the capacity validation of the heat exchanger which provides the heating or cooling of the air supplying the vehicle. Because of the high dimensionality and complexity of the whole task, the number of simplifications in the form of proper boundary conditions and constraint equations was proposed by authors. The presented paper contains the presentation and discussion of the used simplifications, the saved computational capacities are accented and results in the form of distribution of thermomechanical quantities are presented. Finally, the capacity of heat exchanger used is validated.
