Thermosolutal Marangoni stagnation point GO–MoS2/water hybrid nanofluid over a stretching sheet with the inclined magnetic field

Abstract

The graphene oxide–molybdenum disulfide (GO–MoS2) exhibited the performance of photocatalytics under solar light radiation and the problem is more significant during Marangoni convection. In this scenario, the thermosolutal Marangoni stagnation point flow over a stretching sheet where the GO–MoS2 nanoparticles are embedded in a base fluid water are taken into consideration. The inclined magnetic field with the Joule heating effect, thermal radiation, chemical reaction and Soret and Dufour effect is introduced in the system. The leading equations are simplified by applying the proper similarity transformation and then solved numerically with the help of the MATLAB bvp4c routine. The impact of several parameters on the velocity, temperature and concentration with other physical properties such as skin friction, local Nusselt number and local Sherwood number has been displayed. Moreover, the results of this paper demonstrate a brief equivalency between nanofluid and hybrid nanofluid. It is experimented that the Marangoni effect arises due to a fluctuation in temperature as well as a chemical reaction. Surface tension refers to mean temperature and mean concentration restricts the fluid velocity. GO–MoS2 exhibits the increase in antimicrobial effects with enhancement in the glutathione oxidation and it is also used for DNA detection. The impact of GO and MoS2 in the flow of hybrid nanofluid shows significance with a huge application in medical science.
