Review of CFD methods for turbomachinery

nasri |  0 comment |  

Deadline for registration: 15 days before the starting date of each training
Duration : 3 days / (21 hours)




The objective is to provide some basics about the numerical simulation of unsteady complex flow in turbomachinery; both for compressors and turbines components. The first part is dedicated to a review of the flow physics that take place in turbomachines (rotor/stator intercations, aerodynamics instabilities, aero-elasticity, turbulence, etc.), providing some guidelines to help designers and scientists to understand and predict these flows. The second part proposes a review of existing methods to compute the flow in these components. State-of-the-art techniques are presented: RANS and LES modeling, harmonic balance technique, etc. Some other emergent techniques (uncertainty quantification, multiphysics and multi-codes simulations) are also discussed.

Target participants

This training session is for engineers, physicists, computer and numerical analysts.

This study focuses on Hall-effect thrusters, which were first invented in the 1960s. Although such systems have been extensively studied, the detailed physics of the magnetized plasmas in these thrusters is very complex and several plasma processes that have direct influence on the thruster...Read more
