Thermal and solutal Marangoni stagnation point Casson fluid flow over a stretching sheet in the presence of radiation, Soret and Dofour effect with chemical reaction

Abstract

The Marangoni flow is involved with microgravity and earth gravity, which causes undesirable effects in crystal growth experiments. Crystal growth experiments were designed in such a manner so as to appraise MIR (space station), which is one of the best platforms for protein crystallization and radiation experiments. In this article, a model is proposed with a stagnation point and a Casson fluid flow at the interface of the plate in the presence of Marangoni convection influenced by a magnetic field and chemical reaction. Furthermore, it is considered that both temperature and concentration surface tension vary linearly with the interface. It is important to choose similarity transformations for implementing nonlinear differential equations into linear ordinary differential equations. We solved the system of differential equations using fourth order Range‐Kutta method with suitable shooting techniques, and the results are displayed through graphs. A comparison is made with the earlier existing literature, and it shows a very good agreement. The results and a detailed discussion of velocity, temperature, and concentration have been shown graphically. The favorable and unfavorable buoyancy force to Marangoni flow, the features of temperature and concentration field, have been investigated.

“…The suction/injection condition at the surface gives a significant impact on the boundary layer flow 40 . Recently, Shaw et al 41 investigated the effects of Soret and Dufour, radiation, and chemical reaction in the presence of a magnetic field with Marangoni convection of Casson fluid.…”

Unsteady MHD chemically reactive double‐diffusive Casson fluid past a flat plate in porous medium with heat and mass transfer

Mixed convection Casson fluid flow about a sphere in the presence of chemical reaction in the system had been discussed by El‐Kabeir et al Recently, Shaw et al carried out the study on the Soret and Dufour effect, thermal and solutal Marangonic convection of a chemically reactive Casson fluid past a stretching sheet.…”

Double dispersed bioconvective Casson nanofluid fluid flow over a nonlinear convective stretching sheet in suspension of gyrotactic microorganism

“…Walter's B nanofluid flow past an electromagnetic sheet has been discussed by Nayak et al 13 with the impact of Cattaneo‐Christov thermal and solutal diffusion. The present problem deals with the base fluid as Casson fluid, which is a special kind of non‐Newtonian fluid with yield stress, and due to rheological features, it is classified as one of the most accepted non‐Newtonian fluid 14‐17 . Bioconvection is a biological phenomenon, which usually occurs due to upswimming of microorganisms, which are less denser than water in suspensions.…”
