In this video, we simulate a flow around a cylinder, a classic problem in fluid mechanics. The highlight
• o-grid type mesh generation
• pisoFoam
• use of forces library to compute Coefficients of Lift and Drag
• Vortex shedding frequency
• Validate with experimental results
After reviewing the physical aspects of flow around a cylinder, we generate a mesh and specify boundary conditions for this problem. The use of forces library to compute Cl and Cd are described in the eBook. A quick look into the pisoFoam algorithm and then we validate the results from the simulation with experimental results.
