“…Marangoni convection frequently occurs in metallurgy, painting and drying, 4 semiconductor production, 5 and production of silicon wafers. It is dominant form of convection in microgravity region or the reduced gravity regions 6,7 . Yu et al 8 simulated the effects of concentration dependent capillary convection in an annular pool.…”

“…It is dominant form of convection in microgravity region or the reduced gravity regions. 6,7 Yu et al 8 simulated the effects of concentration dependent capillary convection in an annular pool. It was concluded that smaller values of soluto-capillary Reynolds number creates steady axisymmetric flow; however, for higher values, a second vortex emerges in the interior of circular pool.…”

This article theoretically investigates the entropy generation in unsteady two-dimensional magnetohydrodynamic flow of Maxwell power-law-fluid past a stretching surface in consideration of thermal and solutal Marangoni convection. The heat and mass transport phenomenon of Maxwell power-law-fluid has been expressed using Cattaneo-Christov double diffusion (CCDD) model. Governing equations are modeled by using Navier-Stokes equations under suitable consideration. The developed mathematical model of the problem is in the form of nonlinear and coupled partial differential equations. Using similarity transforms, governing equations are converted into non-linear coupled ordinary differential equations (ODEs) whose numerical solutions have been obtained using Bvp4c routine in MATLAB. Through numerous graphs, a thorough analysis of entropy generation and Bejan number is conducted. It has been observed that the fluid velocity gets accelerated for higher values of thermal and solutal Marangoni parameters in the boundary layer.

“…Nandi and Kumbhakar [24] analyzed the flow of tangent hyperbolic nanofluid flowing over a wedge under Hydromagnetic assumptions. Tripathi [25] discussed the flow of hybrid nano-liquid past an elongating disk by considering the effect of Marangoni convection. He found that the use of blade-shaped nano particles in hybrid nano-liquid result in maximum heat transfer at the disk surface.…”

In the present research article, we address the magnetically controlled thermal and solutal Marangoni convection in the flow of self-rewetting power-law liquid over a disk, in the existence of a space dependent heat source. The self re-wetting property of fluid is modelled by considering a quadratic dependence of surface tension on temperature and species concentration. The aforementioned problem is modelled by simplified Navier-Stokes equations. Identifying the appropriate transform variables is essential for developing ordinary differential equations from original partial differential equations that describe the flow conditions. The resulting ordinary differential equations are solved by using the bvp4c routine of MATLAB and numerical solutions are presented via Graphs and tables, illustrating the impact of several factors on fluid velocity, temperature, and concentration. Computation of the quantities of physical interest such as Nusselt and Sherwood numbers are also done from those numerical solutions. One of the key findings of present research work is that the Marangoni convection works differently for pseudo-plastic fluid and dilatant fluid.On increasing thermal Marangoni convection the temperature of dilatant fluid reaches a peak value much closer to the disk than temperature of pseudo plastic fluid.

“…Ganesh et al 6 discussed Marangoni convection in the flow of normalAl 2 normalO 3-nanofluid under the influence of the magnetic field. Recently, Tripathi 7 discussed the Marangoni convection in the thin film of hybrid nanofluid over a disk and showed that an increase in interfacial tension tends to accelerate the velocity of the hybrid nanoliquid. In the last few years, it has been established that for certain fluids, surface tension is not necessarily a decreasing function of temperature.…”

In this study, the influence of gravity-driven convection and Marangoni convection due to the temperature-dependent surface tension gradient on the rise of an axisymmetric bubble moving in another fluid in a self-rewetting system inside a rectangular tube is studied in the presence and absence of a magnetic field. The axisymmetric bubble (fluid 1) moving in another fluid (fluid 2) is considered immiscible. A two-dimensional cylindrical polar coordinate system has been chosen to present the sketch of the problem. Partial differential equations governing the mentioned flow situations are written and converted into non-dimensional forms and their analytical solutions have been obtained. The deformation in the bubble in the form of its radius and length is simulated. The motion of the droplet is also analysed in the microgravity region by graphing the position of the bubble. The graphical results show that there is a decrease in the contribution of the Marangoni effect and gravitational effect when the magnetic field is increased. In the absence of a magnetic field, the contribution of both the Marangoni effect and gravitational effect decrease on increasing the relative viscosity.
