Concentric Tube Heat Exchanger

Application ID: 22211

This app demonstrates the following:

  • Selecting predefined or user-defined materials
  • User option to switch between laminar flow or turbulent flow
  • Changing boundary conditions using methods
  • Visualizing temperature dependent material properties as graph plots
  • User option to set the solver tolerance

Finding the right dimensions for a heat exchanger is imperative to ensure its effectiveness. Other properties must also be considered in order to design a heat exchanger that is both of the right size and provides heated or cooled fluid of the right temperature.

The app computes these quantities for a heat exchanger made of two concentric tubes. The fluids can flow either in parallel or in counter current flow.

The fluid properties, heat transfer characteristics, and dimensions of the heat exchanger can all be varied. The Nonisothermal Flow multiphysics interface is used to model the heat transfer.

This application example illustrates applications of this type that would nominally be built using the following products:
