Due to the absorption properties of water, solar visible and near-infrared irradiance induces a volumetric heat source with exponential decay. Three different scenarios of mixed natural and forced convection are discussed: two fully-developed flows in vertical flat and rectangular channels and a developing flow in a slender channel with a rectangular cross-section (similar to a Hele-Shaw cell). Three cases of temperature boundary conditions are studied for the lighted and the opposite walls, whereas in the case of the rectangular channel, linear declination of the side wall temperatures is applied. Analytical solutions for fully-developed flows in both flat and rectangular channels are reported and discussed. Some physical characteristics of the flows such as bulk liquid temperature and Nusselt number are calculated. The problem of developing flows in the slender rectangular channel is formulated in a “stream function-vorticity” version. The main conclusion is that the presented models predict quite well the average physical parameters of the mixed convection flows in the glazing chamber under solar radiation.","PeriodicalId":49980,"journal":{"name":"Journal of Theoretical and Applied Mechanics","volume":"26 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135272400","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}

The Euler-Lagrange equations in generalized coordinates of this model are deduced by the nonconservative Hamilton principle. The Noether symmetry criterion and conserved quantities based on the Lie point transformation group are given. The influence of external non-potential forces and material parameters on the forms of Noether conserved quantities is detailed discussed, which indicates that the conserved quantities are very depending on the loading rate and mechanical parameters of the membrane.","PeriodicalId":49980,"journal":{"name":"Journal of Theoretical and Applied Mechanics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136157100","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}
