Problem overview

This tutorial simulates dual heat exchanger using the two fluid heat exchanger method. The model consists of inlet, outlet and radiator for the main fluid (air) and a linked radiator volume for the secondary fluid (coolant). Air enters with a velocity of 4 m/s at 303 K and leaves at a pressure of 101325 Pa. The coolant enters with a mass flow rate of 3 kg/s and leaves at 101325 Pa. The following two simulations are performed:

Coolant inlet temperature 373 K is specified and the heat rejection rate is predicted.
Total heat transfer 160 kW in the heat exchanger is specified and the coolant inlet temperature is predicted.
