Abstract

This comparative study inspects the MHD three-dimensional revolving flow and temperature transmission of a radiative stretching surface. The flow of nanofluid is modeled using the Tiwari and Das model. Water is the base fluid, and the nanoparticles are composed of two different types of nanoparticle, i.e., gold and silver (Au and Ag). The non-radiative heat flow notion is examined in a temperature field that results in a nonlinear energy equation. Conformist transformations are used to generate a self-similar arrangement of the leading differential system. The resulting system has an intriguing temperature ratio constraint, which shows whether the flow has a little or significant temperature differential. By using a powerful mathematical technique, numerical results are obtained. The solutions are influenced by both stretching and rotation. The difference in velocity constituents with the elements’ volume fraction is non-monotonic. Results for the rotating nanofluid flow and heat transfer properties for both types of nanoparticles are highlighted with graphs. The impact of physical concentrations, such as heat flux rates and skin friction constants, are examined at the linear extending surface and clarified graphically. Ag-water nanofluid has a high-temperature transfer constant compared to Au-water nanofluid. The velocity profile was also discovered to have a parabolic distribution shape.

Summary

Introduction

Problems associated with pouring in a spinning setting occur in many fields, such as engineering and geophysics. The engineering applications of pouring in a spinning setting occur in a large range of chemical industries, the processing of food, centrifugal filtration processes, the design of the multi-pore supplier in the gas-solid liquidized bed, rotating machinery, and in manufacturing processes. By using a regular perturbation approach, he found a series of solutions. Rajeswari and Nath [2], and Nazar et al [3] furthered Wang’s efforts concerning unstable flow problems. Their outcomes specify a seamless alteration from the initial unstable flow to the end smooth state flow. Vajravelu and Kumar [4]
