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:
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 Specification Chart 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.
