3D NUMERICAL ANALYSIS OF A SHELL-AND-TUBE HEAT EXCHANGER

In this paper, a three-dimensional mathematical model is developed and implemented. The turbulent numerical model solves a conjugated heat transfer problem in a shell-and-tube heat exchanger for different inlet conditions. Results indicate the existence of a zigzag flow pattern and that the increase of the air velocity (sellside) increases the heat transfer coefficient and the presseur drop and decreases the air outlet temperature.
