Additionally, the superposition of multiple scales of roughness in largely unexplored. This study investigates the heat transfer augmentation of two scales of patterned roughness, both individually and combined, where the large-scale roughness exceeds 20% of the boundary-layer height. These mimic technical roughnesses from the original experiments from Nikuradse low-speed experiments. The experiments were undertaken in a Ludwieg tunnel at a nominal Mach number of 5 and unit Reynolds number of [Formula: see text]. Determination of the Stanton numbers were performed by combining measurements of the freestream total temperatures with the measurement of the heat transfer from calorimeter and thin-film heat transfer gauges. Results indicate trends toward bulk heat transfer augmentation of order 20, 40, and 50% with increased [Formula: see text] for the small-, large-, and multiscale roughness patterns tested, respectively. For the large-scale roughness pattern investigated, significant heat transfer suppression was measured in the troughs between the elements; enhancement was measured to be substantial on the peaks, with notable difference distinguished between the spans and the intersections of the elements.","PeriodicalId":17482,"journal":{"name":"Journal of Thermophysics and Heat Transfer","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140362387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
