Introduction

This video demonstrates the simulation of a cross-flow heat exchanger using ANSYS Fluent software. The presenter, Muhammad Ahmed, guides viewers through the modeling process, from geometry creation and meshing to setting up boundary conditions and running the simulation to generate temperature and velocity contours.

Key Takeaways

• The video details the step-by-step process of creating a cross-flow heat exchanger model in ANSYS DesignModeler.
• It covers meshing techniques in ANSYS Meshing, including the use of edge sizing for refined mesh around pipes and the rectangular body.
• The video explains how to set up boundary conditions in ANSYS Fluent, including specifying inlet velocities, temperatures, and material properties for both hot and cold fluids.
• The simulation is run with specific parameters (SIMPLEC scheme, Green-Gauss cell based gradient, etc.), and the results are visualized using streamlines and vectors.
• Named selections are used to define inlet, outlet, and pipe boundaries for easier management during the simulation setup.

The video uses the following boundary conditions:

• Heated pipe inlets (1-6): Velocity = 0.001 m/s; Temperatures ranging from 400 K to 450 K (10 K increments between each inlet).
• Heated pipe outlets (1-6): Pressure outlet.
• Inlet (cold inlet): Velocity = 0.002 m/s; Temperature = 300 K.
• Pipe wall: Material = steel.
