Double-Pipe Heat Exchanger
Application ID: 17083
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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Спецификация and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
