<Accordion title="Transcript">
  This is the second of three courses in our heat exchanger learning pack that take you through creating a heat exchanger from conceptual design to the final part.

  In this course, we will understand how to design baffles to prevent fluids from mixing and lengthen the fluid flow path to the core. Get familiar with the key considerations for designing plenums to evenly distribute flow, and learn basic meshing techniques to export a heat exchanger.
