Wind Tunnel Simulation of a streamlined body in OpenFOAM

This OpenFOAM case simulates a steady-state wind tunnel test for a random streamlined body defined by a CAD file (body.stl). The goal is to evaluate the aerodynamic performance, specifically calculating the drag coefficient of the body in a controlled airflow environment.

Project Structure

• /constant/triSurface directory/body.stl: Contains the geometry of the test body.
• /system, /constant, /0: Standard OpenFOAM directories with setup files for boundary conditions, mesh, and solver configuration.
• /gnuplot: Contains a gnuplot script to plot the drag coefficient.
• /postprocessing: Contains simulation results.

Running the simulation

Easy way: run ./Allrun

Results and Analysis

• Processed results are stored in /postprocessing and in the time directories.
• Use the gnuplot script to visualize the evolution of Cd.

Requirements

• OpenFOAM version compatible with the case files - Tested with v2012, but it must work with the majority of OpenFOAM.com versions.
• Gnuplot for plotting drag coefficient and residuals.

Possible changes

• Change body.
• Increase wind tunnel size.
• Extend analysis to include lift and moment coefficients.
• Add transient case for time-dependent flow analysis.
• Refine mesh for increased accuracy in critical flow regions.
