Effects of meshing strategies on in-cylinder flows

The presentation shows the impact of different meshing strategies on the simulation of the in-cylinder flow structure of the Transparent Combustion Chamber (TCC) engine. Large Eddy Simulation of several consecutive engine cycles are compared to experimental measurements, and the impact of the adopted meshing trategy on both accuracy and computational efficiency is evaluated.

Mesh adaption for vehicle aerodynamics simulation

All major automotive OEMs require fast and reliable processes  for virtual simulation in order to steer a design process that proceeds at an increasingly tight pace.
