Testing the influence of TiO2-Ag/water on hybrid nanofluid MHD flow with effect of radiation and slip conditions over exponentially stretching & shrinking sheets

There are number of previous research studies which focuses on usage of hybrid nanofluids for improving heat transfer rather than nanofluids is one of the most crucial tasks among others. As a consequence, this research paper examines the flows of magnetohydrodynamic(MHD) caused by an exponentially stretching or shrinking sheet of hybrid nanofluids by the heat transfer. Titanium oxide(TiO2) and silver(Ag) nanoparticles and base fluid as water form a novel type of hybrid nanofluid. With similarity transformation applied, the governing partial differential equation is transformed in terms of nonlinear coupled ordinary differential equations. The problem-solving process is achieved using a numerical solver called Matlab bvp4c tool, and dual solutions are achieved. On the other hand, the effects of nanoparticles on many relevant factors, the velocity and temperature profiles, Nusselt number and skin-friction are investigated and displayed graphically in the form of graphs. The analysis of stability studied in this research paper concludes that the first solution is only regarded to be the physical solution. The study concluded that increases in volume fraction of sliver nano-particle result into increase in the skin-friction and Nusselt number. However, the temperature is increased owing to the nano-particles. The skin-friction coefficient decreases on the .1 < 0 shrinking surface region, but the opposite effect is shown on the .1 > 0 stretching surface when the velocity slip(S1) parameter is increased whereas the Nusselt number has the opposite effect. The computations were performed using the bvp4c MATLAB tool on the PARAM Shavak high-performance computing (HPC) system.

Automated summary

This research paper investigates the magnetohydrodynamic(MHD) flows caused by an exponentially stretching or shrinking sheet of hybrid nanofluids in terms of heat transfer. The study concludes that an increase in the volume fraction of silver nanoparticles leads to an increase in skin-friction and Nusselt number, while temperature increases. When the velocity slip(S1) parameter increases, the skin-friction coefficient decreases on the shrinking surface region but has the opposite effect on the stretching surface region, while the Nusselt number has the opposite effect as well.
