Cross-Flow Heat Exchanger
Application ID: 173
This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells. The model takes heat transferred through both convection and conduction into account.
A square cross-section is used for the fluid channels instead of circular cross-sections, often used in micro heat exchangers. The heat exchanger is of cross-flow configuration and can consist of about 20 unit cells. Because the unit cells are almost identical except for edge effects in the outer cells, you can restrict the model to a single unit cell.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
