In the case of an electric vehicle, it could increase the\u0000 range of the vehicle, and in the case of conventional internal combustion engine\u0000 vehicles, it means lower fuel consumption (and consequently lower CO2\u0000 emissions). These discs are typically characterized by complex internal\u0000 geometries, further complicated by the presence of drilling holes on both\u0000 friction surfaces. To estimate the aerothermal performance of these discs, and\u0000 for the thermal management of the vehicle, a reliable model for predicting the\u0000 air flowing across the disc channels is needed. In this study, a real\u0000 carbon-ceramic brake disc with drilling holes was investigated in a dedicated\u0000 test rig simulating the wheel corner flow conditions experimentally using the\u0000 particle image velocimetry technique and numerically. The simulation was\u0000 performed using the moving reference frame (MRF) approach and the experimental\u0000 data were used to validate the numerical model. The results show that drilling\u0000 holes contribute to about 13% of the inlet mass flow and more than 86% of the\u0000 air driven into the brake disc comes from the main inlet of the disc. Moreover,\u0000 the numerical results are in an agreement with experimental data, supporting MRF\u0000 approach as a suitable model for the analysis of complex flows in complicated\u0000 geometries.","PeriodicalId":503275,"journal":{"name":"SAE International Journal of Passenger Vehicle Systems","volume":"26 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139387015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
