TL;DR: It is shown that the flow field of the evaporating liquid is strongly affected by the presence of the thermocapillary convection, and when the results obtained from both water and organic liquids are compared, they give further insight into the nature of thermocAPillary convections.

TL;DR: In this paper, the thermal assessment of Sutterby nanofluid containing the gyrotactic microorganisms with solutal and Marangoni boundaries is discussed, where the applications of melting phenomenon and thermal conductivity are also considered.
Abstract: This research communicates the thermal assessment of Sutterby nanofluid containing the gyrotactic microorganisms with solutal and Marangoni boundaries. The applications of melting phenomenon and thermal conductivity are also considered. The flow is confined by a stretched cylinder. The prospective of Brownian motion and thermophoresis diffusions are also taken account via Buongiorno nanofluid model. The problem is formulated with help of governing relations and equations which are altered into dimensionless form via appropriate variables. The numerical scheme based on shooting scheme is employed to access the solution. A comparative analysis is performed to verify the approximated solution. The observations reveal that the velocity profile enhanced with the Marangoni number while a declining velocity profile has been observed with Sutterby nanofluid parameter and Darcy resistance parameter. The nanofluid temperature get rise with thermal conductivity parameter and thermal Biot number. An arising profile of nanofluid concentration is observed for concentration conductivity parameter and buoyancy ratio parameter.

TL;DR: A finite-difference/front-tracking method is developed for simulations of soluble surfactants in 3D multiphase flows and it is found that surfactant-induced Marangoni stresses counteract the shear-induced lift force and can reverse the lateral bubble migration completely.

TL;DR: In this paper, single bubble velocity profiles for a 0.8 mm diameter bubble in solutions of Triton X-100 are simulated by solving the Navier-Stokes equation combined with the Marangoni effect under pseudo-steady state conditions assuming the stagnant cap model and applying different mass transfer control steps.

TL;DR: In this paper, it is pointed out that the surface phenomenon MC is sensitive to numerous kinds of surface perturbations thus resulting in unsteady MC and that time dependent MC will generate time dependence of the buoyant flow in the whole melt volume due to intimate coupling of both phenomena.
