Grounded in the FIK and RD identities, this method provides a clear physical and reliable interpretation suitable for arbitrary-curvature profiles. Utilizing this method, an analysis of the aerothermodynamic characteristics of the bistable states of curved compression ramp flows was conducted. The results reveal that the generation of undisturbed and peak Cf is dominated by viscous dissipation. Specifically, flow separation happens when all of the energy input from the work exerted by the adverse pressure gradient (APG) is insufficient to be entirely converted into local viscous dissipation and kinetic energy. Furthermore, the propensity for flow separation at higher wall temperatures is firstly elucidated quantitatively from the perspective of the work by the APG. The peak heat flux is predominantly triggered by the work of viscous stress, with the secondary contribution from energy transport playing a more significant role in the generation of the peak heat flux of the separation state than that of the attachment state.<\/jats:p>","DOI":"10.3390\/sym16091147","type":"journal-article","created":{"date-parts":[[2024,9,4]],"date-time":"2024-09-04T04:28:28Z","timestamp":1725424108000},"page":"1147","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Local-Energy-Conservation-Based Decomposition Method for Wall Friction and Heat Flux"],"prefix":"10.3390","volume":"16","author":[{"given":"Mingzhi","family":"Tang","sequence":"first","affiliation":[{"name":"Hypervelocity Aerodynamics Institute, China Aerodynamics Research and Development Center, Mianyang 621000, China"},{"name":"National Key Laboratory of Aerospace Physics in Fluids, Mianyang 621000, China"}]},{"given":"Wenfeng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Hypervelocity Aerodynamics Institute, China Aerodynamics Research and Development Center, Mianyang 621000, China"},{"name":"National Key Laboratory of Aerospace Physics in Fluids, Mianyang 621000, China"}]},{"given":"Yanchao","family":"Hu","sequence":"additional","affiliation":[{"name":"Hypervelocity Aerodynamics Institute, China Aerodynamics Research and Development Center, Mianyang 621000, China"},{"name":"National Key Laboratory of Aerospace Physics in Fluids, Mianyang 621000, China"}]},{"given":"Gang","family":"Wang","sequence":"additional","affiliation":[{"name":"Hypervelocity Aerodynamics Institute, China Aerodynamics Research and Development Center, Mianyang 621000, China"},{"name":"National Key Laboratory of Aerospace Physics in Fluids, Mianyang 621000, China"}]},{"given":"Yanguang","family":"Yang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Physics in Fluids, Mianyang 621000, China"},{"name":"China Aerodynamics Research and Development Center, Mianyang 621000, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.2514\/3.11985","article-title":"Experimental, Analytical, and Computational Methods Applied to Hypersonic Compression Ramp Flows","volume":"32","author":"Simeonides","year":"1994","journal-title":"AIAA J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1017\/S0022112095002229","article-title":"Experimental and Computational Investigations of Hypersonic Flow about Compression Ramps","volume":"283","author":"Simeonides","year":"1995","journal-title":"J.
