About the Course

BACKGROUND

The main task of a CFD engineer or scientist is using a readily available software to solve problems or developing a code to test new algorithms. To complete the mentioned task, a fundamental understanding of formulating CFD problems is essential. This include correct representation of initial and boundary conditions, sanity and convergence checks and meshing related issues. In addition to establishing basics of CFD, this workshop will also discuss some practical knowledge essential for both practicing engineers, graduate students and scientists. The course will cover aerospace flows, incompressible flow problems, heat transfer and biomedical flow problems. Participants will have opportunities to discuss their problems of CFD with the instructor. : The main task of a CFD engineer or scientist is using a readily available software to solve problems or developing a code to test new algorithms.
