Three levels of variation were adopted for each design parameter (the wall thickness-to-slot width ratio H/S=5.0, 7.0, and 15.0, and injection angle α =30 °, 45 °, and 60 °). Film cooling effectiveness was measured using the pressure sensitive paint technique in a flat plate test rig under 30 m/s of mainstream velocity condition. Four blowing ratios (M=0.25, 0.5, 0.75, and 1.0) defined as the mass flux ratio between the coolant and the mainstream were considered. Carbon dioxide gas was used as the coolant, resulting in a coolant-to-mainstream density ratio of approximately 1.5. The results showed that higher film cooling cooling effectiveness was observed for a wider slot at a constant blowing ratio condition because more amount of coolant was injected through the wider injection area. In contrast, a narrower slot had a benefit for film cooling effectiveness at a constant mass flow ratio condition. Results also indicated that a steeper injection angle caused lower film cooling effectiveness due to stronger mixing between the coolant and the mainstream.","PeriodicalId":338979,"journal":{"name":"The KSFM Journal of Fluid Machinery","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116616728","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}
