Stability analysis of diamond-silver-ethylene glycol hybrid based radiative micropolar nanofluid: A solar thermal application

Abstract

The current study emphasizes the stagnation point flow and heat transmission properties of a hybrid-based micropolar nanofluid over a porous Riga plate that is capable of both shrinking and stretching. A mathematical modeling of diamond-silver-ethylene glycol/water hybrid nanofluid has been explored. Here 20% of ethylene glycol and 80% of water are considered as the base fluid. Heat transfer proficiency of airplane wings is evaluated with the inclusion of distinguished effects like viscous dissipation and solar-based thermal radiation, so we included them in this paper. By employing some suitable transformations, the system of nonlinear ordinary differential equations are attained and numerically solved by using MATLAB software. The dual nature of skin friction, Nusselt number, and micro-rotation gradient solutions are demonstrated for a wide variety of relating parameters. The boundary-layer separation happens when number of results fails to happen ahead of the critical value of the contracting parameter. To show the effect on flow and heat transfer of appropriate parameters, graphs are used. Stability is shown to be better in solution one than in the second, according to the results. It is detected that the temperature has decelerated in the presence of micropolar heat conduction parameter for both solutions The radiation parameter reduces the Nusselt number of the hybrid nanofluid for the first solution and a contrary for second solution. The array of the skin friction values are moving downwards for fluctuating values of heat source/sink. Sun based energy is the chief source of heat from the sun, and it utilizes in photovoltaic cells, sun-based power plates, photovoltaic lights and sun-based hybrid nanofluids. Specialists are currently exploring the utilization of nanotechnology and sun-based radiation to further develop flight effectiveness.
