Heat Exchanger Pipe

Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow through the system, the material properties of both change with the varying temperature. The model uses the Nonisothermal Flow multiphysics interface, within the Heat Transfer Module, to show the temperature field and velocity magnitude throughout the pipe system.
