Abstract: A roughened solar air heater is developed numerically and experimentally with a novel roughness in the absorber. The roughness incorporated is a combination of rectangular and semi-circular ribs. The analysis is done to ...

Abstract: To transport the energy efficiently without much dissipation, first and second law analyses of mixed convection heat transport from an array of nonisothermal rectangular vertical platefinned heat sink are made using purely ...

Abstract: Boussineśq and non-Boussineśq fluid with thermo-physical property variation have been investigated for a vertical fin array. Computations are executed for the range of parameter such as Grashof number 1.86 × 105 and 4.42 ...

Abstract: This study conducts an experimental assessment to investigate the influence of black gravel and cylindrical cement fins as thermal heat storage materials in a single-slope solar still. The trials are performed under the ...

Abstract: A computational analysis of conjugate mixed convection heat transfer from shrouded vertical nonisothermal heat sink on a horizontal base is performed. The overall Nusselt number and the product of friction factor (f) and ...

Abstract: More than 2 billion people globally depend on biomass for cooking, predominantly using conventional cookstoves. This leads to approximately 4 million annual deaths due to indoor air pollution. Currently, air pollution ...
