Numerical study of squeezing unsteady 〖Fe〗_3 O_4 and TiO_2-nanofluid flow in the presence of thermal radiation and heat generation /absorption
Abstract
In this study, a numerical investigation of squeezing transient nanofluids flow between two parallel plates is considered. The impacts of radiant heating and thermal generation/absorption across the temperature profile were scrutinized. the Runge-Kutta fourth-order method (RK4) with shooting scheme was used to solve the two-dimensional non-linear momentum and energy equations. It has been observed that both negative and positive squeezed numbers have a peculiar significant influence on the velocity profile. Moreover, it is quite ostensible that the moment nanoparticles are being augmented into the fluid, the heat transfer is enhanced, due to their great thermal conductivity feature. It is also perceived that, incrementing the radiative parameter results in a decrease in the temperature profile, while the fluid temperature is physically ascending in the cause of thermal generation but diminishes in the cause of thermal absorption respectively. The result shows the mutual agreement between the nano-sized Fe3O4 and TiO2, though with a slight high upturn in thermal boundary layer thickness with TiO2 than Fe3O4.
