Entropy Generation Parallel Analysis and Optimised Efficiency of a Wavy Solar Collector

The current paper is aimed to study entropy generation analysis and natural convective flow of -water based nanofluid filled inside wavy solar collector with right-angled triangular cross sectional area. The flow is assumed to be steady, laminar and incompressible with double diffusive convection. The set of governing equations are the conservation of mass, momentum, energy and concentration which have been solved by implementing the Parallel approach of Element free Galerkin method using parallelism of graphic processor units (GPUs) involving six physical cores (12 logical cores) of Intel® Xeon® E5645 CPUs at 2.40 GHz. The effect of various parameters namely Dufour effect, Soret effect and Schmidt number on the isotherms, iso-concentration, streamlines, average Nusselt number and Sherwood number have been studied. The results show that the waviness of the slant cover plate results in perturbation in the flow which has significant effect on the heat transfer rate because of the increased surface area. The parallel approach of the meshfree technique has improved the computational efficiency which is a novel contribution.
