Abstract

Because of thermal characteristics and the intention of improving heat transfer rate, the issue of hybrid nanofluid has become an intriguing subject for academicians and researchers in the contemporary technological period. This report presents the impacts of thermal radiation and viscous dissipation on the motion of the hybrid nanofluid of (Cu + Al2O3)‐H2O over a moving surface. The present flow model is simulated by a set of nonlinear partial differential equations (PDEs), which are converted into a system of ordinary differential equations (ODEs) by the appropriate similarity transformations. After that, the obtained ODEs are resolved numerically by bvp4c in MATLAB. The thermal radiation parameter has been shown to improve the rate of heat transfer and increase the temperature of the hybrid nanofluid (Cu + Al2O3)‐H2O. Moreover, two branches of solutions that depend on the stretching/shrinking parameter values are noticed. Furthermore, the stability results show that the upper branch can be used in practical applications, due to its stable nature. [ABSTRACT FROM AUTHOR]
