Computational Fluid Dynamics (CFD) is the science of using computers to predict liquid and gas flows based on the governing equations of conservation of mass, momentum and energy. Through CFD, we can analyze, understand and predict the fluids that make up nearly every part of our world. Thus, it is of utmost importance for nearly every graduate from Mechanical or Aerospace engineering to have a basic understanding of CFD simulations and how it works. This webinar will discuss basics of simulations, governing equations and their discretization techniques, meshing and associated best practices, setting up appropriate boundary conditions and the tips and tricks for reducing computational time and finally some aspects of post processing including flow visualization.
