Abstract
MAHLE is a leading international development partner and supplier, as well as a pioneer and technology driver for the mobility of the future through its 5 business units and 4 profits centers. Focusing on our engine cooling portfolio, fully integrated solutions are proposed including frame, radiators, fan module... Performance and acoustic requirements for the rotating fan and surrounding parts are becoming more challenging with all-electrical cars. Therefore, Mahle uses CFD to provide the best compromise between performance (pressure drop, noise level) and cost for the fan concept but also for all linked products. On this presentation, Mahle would like to show How SIMULIA PowerFLOW is implemented and used to comply with the strict requirements that these products require. As a practical example, a small study on the noise generated by a static component will be explained. This element of the cooling module – called air duct - links the radiator or fan module to the air inlet of the car. Different packaging requirements are freezing partially the air duct design. So as first step Mahle focused on the understanding of the air duct noise impact in order to optimize the full cooling module acoustics.
Presenter Bio
In 2012, Florian Mayot graduated from the French engineering school ENSTA-Bretagne and the Czech Technical University with a European Master of Automotive Engineering. After a master thesis in a pre-development department about engine warm-up, his first job was in Stuttgart as a Simulation Engineer with the target to dimensionnate thermodynamically cooling modules (Radiator, Fan…) for different OEMs. After two years, he moved to Luxembourg for the same function but with extended component responsibility (AC-loop). From this position, he switched to technical project leader (global responsibility for international projects) which was based first in Luxembourg and later in Poland. After leading successfully projects to SOP, Mahle gave him a new opportunity by reinforcing the fan simulation capacity, starting from July 2021. In order to better answer customer requirement, he enrolled himself to the Master Online Akustik from the Stuttgart University.
