The application of fluid flow through a rotating disk in a solar thermal power plant can help in increasing energy production, reduce costs, and improve the overall efficiency of the system. The concentrated solar power (CSP) technology can help in assisting solar energy for sustainable power generation. This work explores the heat transfer assessment of magnetized tangent hyperbolic fluid flowing over a porous rotating disk under the effects of thermal radiation, convective heating, Ohmic heating and viscous dissipation. The solution of transformed ODEs is obtained by the Legendre wavelet collocation method (LWCM). To visualize the impact of acting variables, the results are portrayed by graphs and tables. From the outcomes, it is noted that the rate of heat transfer is enhanced up to 84.79% with an increase in radiation parameter. Moreover, the radial velocity enhances as the rotation parameter is accelerated. The dual behavior in temperature outlines is obtained due to escalated values of the porosity parameter. For the validation of the present results, a tabular comparison is shown with earlier work. [ABSTRACT FROM AUTHOR]
