摘要:The heat transfer ratio plays an important role in the production sector, and hybrid nanofluid has more heat transfer as compared to the base fluid. Two sorts of hybrid nanofluids have been used for heat enhancement applications. The present research paper is aimed at investigating an approximate analytical study of time-dependent MHD Casson hybrid nanofluid on an extending surface along with thermal radiation. The novelty of present research is that the first time-dependent Casson MHD flow of hybrid is addressed analytically in the form of a series solution along with flexible properties on an extending surface. Transforming the nonlinear partial differential equation to nonlinear ordinary differential equation, we used the defined similarity transformation. The governing nonlinear equations are solved with help of the approximate analytical method presented by Liao. The impact of different parameters like Casson parameter, unsteady parameter, magnetic field parameter, porosity parameter, Prandtl number, Eckert number, radiation parameter, and Grashof number is presumed in the form figures for velocity and temperature profile. The current research article has a good comparison with the previously published work.
