CFD Based Simulations on CL-CSP System
Abstract: The current study deals with research on CL-CSP plant system carried out analytically. The research also includes CFD based simulations among three models, mainly model 1, model 2, and model 3. Model 1 consists of straight pipe; Model 2 consists of Zig-zag pipes and Model 3 consists of helical pipes. The results were evaluated for heat flux, outlet temperature, velocity gradients, turbulent, eddy viscosity etc. under the conditions for presence …

Investigation of Heat Transfer in Concentric Annuli with Perforated Inserts
Abstract: The increasing necessity for saving energy and material imposed by the diminishing world resources and environmental concerns have prompted the development of more effective heat-transfer equipment with improved heat-transfer rates. The hydrodynamic boundary layer acts as main resistance for the transfer of heat from tube surface to fluid or vice-versa and many researchers are trying to improve the convective heat transfer rate with inserts in tubes to break the boundary …
