Numerical development of heat transfer correlation in asymmetrically heated turbulent channel flow

This study deals with forced convective heat transfer. It is divided into two parts. Firstly, a review of transfer involving convection in tubes and channels proposed. In the case channel geometry, studies dealing symmetrically asymmetrically heated flows as well one side are reported. Then, new correlation for associated turbulent flow developed using Large Eddy Simulations. The Proposed Correlation, also referred to PC, involves specific term handle asymmetric conditions. domain covered by simulations following: fluxes vary between 4 580 kW/m2, Prandtl number ranges from 0.76 3.18 bulk Reynolds 10 600 177 000. Three correlations literature compared proposed this paper. conventional expressions tend overestimate Nusselt at hot independently temperature ratio. They, also, underestimate cold side, especially when close wall temperature. provides great results both heating global accuracy each quantified.
