BMW M6 geometry clean up and surface meshing using ANSA

  Surface Wrapping Surface wrapping is a method of extracting the desired surface with the desired volume of interest to perform CFD analysis. Surface wrapping does not incorporate all the minor details of the inside of the geometry, it only takes the outer detail of the geometry. When the CAD file contains a lot…

Objective: Create the Ahmed Body slant for both 250 and 350 Run Steady-state implicit coupled flow simulation Use the turbulence models K-OmegsSST and k-epsilon Validate the velocity profile along the Ahmed body at different points with the experimental data. Calculate the cd and cl using the different turbulence.…

NACA The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section…

Objective Discuss some practical CFD models that have been based on the mathematical analysis of Rayleigh Taylor waves. And explain how these mathematical models have been adapted for CFD calculations. Perform the Rayleigh Taylor instability simulation for 3 different mesh sizes with the base mesh being 0.5 mm. Compare…
