Renewable energy technology for the sustainable development of thermal system with entropy measures

The idea of hybrid nanofluid is used to show the renewable energy technique for the thermal conductivity of nanofluids. Two types of nanoparticles namely silver and aluminum oxide are used for the hybrid nanofluid Ag-Al2O3/H2O. Gyrotactic microorganisms motion and entropy generation are also the part of present study investigation. Governing equations of the problem are transformed into ordinary differential equations through the application of appropriate similarity transformations describing leading edge accretion/ablation phenomena which have been solved through the homotopy analysis method. The non-dimensional parameters are noted for playing their roles in investigating activities of hybrid nanofluid flow, heat transfer, nanoparticles concentration, gyrotactic microorganisms concentration and entropy generation rate. Comparison of the present work is shown in table which provides an excellent agreement with the published work. (C) 2019 Elsevier Ltd. All rights reserved.
