Accurate impeller-volute interaction CFD simulation in turbocharger design

Accurate impeller-volute interaction CFD simulation in turbocharger design

Turbochargers are currently ubiquitous in automobiles. It is nearly impossible to find a new Diesel vehicle without turbocharging and direct injection. Gasoline cars have been also following suit for the past few years. Regulations are pushing for lower emissions and the way to achieve this has been downsizing and using turbocharging to offset the lower power density of a smaller motor.

NASA Glenn Research Center: Integrated fluid dynamics - acoustics simulation approach of aircraft fan noise

An innovative computational approach, integrating mesh generation, CFD simultaneous analysis of noise source and propagation, with acoustic radiation, is presented and applied to the simulation of the Advanced Noise Control Fan (ANCF) developed by NASA Glenn Research Center.
