Reduce fuel consumption by optimizing engine parts with CFD
How to reduce the carbon footprint of the automotive industry? Mobility comes with huge CO2 emissions and drastically reducing them is a top priority for vehicle designers today. It is not surprising that simulation can play a major role in finding solutions to this important challenge. Simulation can provide insights, reduce time to market, improve reliability, and reduce engineering costs for designing new and optimized vehicles.
Renault understood this very well. In response to rapidly changing market demands and environmental pressures, they push the design of every component of their engines to maximum efficiency and use computational fluid dynamics for the optimization of pumps, turbochargers, fans, etc Everything to obtain maximum performance, with minimum consumption.
“CFD simulation and optimization tools are key players at Renault and in the automotive industry in general at the moment (…) We selected Cadence CFD for its long experience and expertise in the digital CFD field, and more especially in rotating machines. We chose it because of the high quality of the mesh and their numerical solutions which give very precise results. We also really appreciate their optimization tools based on parameterized CAD data,” said Alain Lefebvre, fluid systems simulation expert at Renault.

To learn more about how Renault specifically uses CFD in its design processes, check out this short on-demand webinar. They tell how they handled a specific case study where they investigated how to optimize their vehicles’ thermal subsystems to reduce their impact on CO2 emissions and comply with WLTC (Worldwide Harmonized Light-Duty Test) Cycle) and how it impacts not only ICE but also xHEV and EV.
