Nonisothermal Flow in a MEMS Heat Exchanger

Nonisothermal Flow in a MEMS Heat Exchanger

This example concerns a stainless-steel MEMS heat exchanger, which you can find in lab-on-a-chip devices in biotechnology. Fluid flows through the tubes while a stainless steel heat sink/source surrounds the tubes.

The heat exchanger is modeled in 3D and accounts for heat transfer through both convection and conduction.

The example includes two models, one that assumes an analytical velocity profile in the tubes, and another that solves for the nonisothermal flow in the tubes.
