Reverse Cross Flow Plate Heat Exchanger

Description: This module introduces beginners to CFD analysis of reverse cross flow plate heat exchangers using ANSYS Fluent, a highly efficient, compact configuration common in HVAC systems and industrial process cooling. The course builds on core plate heat exchanger concepts by focusing on the cross flow arrangement's distinct plate layout and flow pattern, and extends into comparing how different flow directions affect thermal performance.

Methodology: The training covers building a simplified cross flow geometry, defining the working fluid and plate material properties, and setting appropriate inlet and outlet conditions for both fluid streams, along with wall and interface boundary conditions to capture realistic heat transfer behavior. Solver parameters and convergence criteria suited to cross flow simulations are configured, and the solution is monitored for stability through to convergence.

Analysis: Results are examined through velocity field and temperature contour visualizations, along with calculated local and overall heat transfer coefficients and exchanger effectiveness. The module also compares co-current and counter-current flow arrangements, evaluating how flow direction shapes temperature profiles and overall heat transfer effectiveness, giving learners a practical basis for informing design decisions in reverse cross flow heat exchanger applications.
