Application Renault evaluates the efficiency of their turbo-compressors through CFD analysis with NUMECA.

Pollution and fuel consumption are the most important features of thermal engines that must be drastically improved in the coming years. In order to achieve this, all consuming parts of cars are being meticulously analyzed to try and decrease losses to the maximum through design improvements, while taking into account inherent negative effects such as condensation issues for the compressor.

It is within this framework that Renault turned to NUMFLO - the consulting group of NUMECA International, which is renowned for its top level expertise in multiphysics design and analysis. The specific focus of the first study was to evaluate the impact of Low Temperature Exhaust Gas Recirculation (LT-EGR) on the efficiency of their turbo-compressors through CFD analysis.
