Rotatory flow of MHD (MoS2-SiO2)/H2O hybrid nanofluid in a vertical channel owing to velocity slip and thermal periodic conditions

Abstract

BackgroundThe present article is a mathematical study on oscillatory pressure-driven MHD flow of a hybrid nanofluid in a vertical rotating channel. Hall current effect along with velocity slip and thermal periodic boundaries are the main focus of the present mathematical analysis. In the present investigation Molybdenum disulfide and silicon dioxide, nano-scaled particles are suspended in water. MethodologyMathematical modeling is carried out by considering rotating frame in the rectangular coordinate system and suitable non-dimensional variables are incorporated for simplification and non-dimensionalization of the problem. The hybrid nanofluid velocity and temperature distributions are derived in closed form with the aid of mathematics software MATHEMATICA. The prominent parameters’ effect on flow and heat transfer is investigated and studied through graphs. Significant findingsIt is concluded that hybrid nanofluid transport is highly influenced by surface roughness within the channel. Mixed convection and rotation parameters contribute to decelerating primary velocity and accelerating secondary velocity for both silicon dioxide as well as MoS2−SiO2 nano and hybrid nanofluids, respectively.
