Magneto-Thermo-Marangoni convective flow of Cu-H2O nanoliquid past an infinite disk with particle shape and exponential space based heat source effects

Results in Physics, 2017
The exponential space dependent heat source (ESHS) process is utilized to explore the thermal transport characteristics of Marangoni convective flow in a Cu-H2O nanoliquid due to an infinite disk. Flow is driven by linear temperature.

Nonstationary Marangoni convection [PDF]

Applicationes Mathematicae, 1999
The author studies nonstationary Marangoni convection in a fluid drop bounded by a free surface with surface tension. The fluid motion inside is governed by incompressible Navier-Stokes equations combined with heat equation. Using energy estimates, Rothe method and fixed point argument, the author establishes existence and uniqueness of solution for ...

Darcy-Benard double diffusive Marangoni convection in a composite layer system with constant heat source along with non uniform temperature gradients

, 2021
The problem of Benard double diffusive Marangoni convection is investigated in a horizontally infinite composite layer system enclosed by adiabatic boundaries for Darcy model. This composite layer is subjected to three temperature gradients with constant

Marangoni convection in V-shaped containers [PDF]

Journal of Engineering Mathematics, 1992
This paper presents a numerical study of the time evolution of Marangoni convection in two V-shaped containers involved in the microgravity experiments reported in Hoefsloot et al.[7]. First the case of the triangular container with a plane gas/liquid interface is considered, next the container having the shape of a circular sector with a curved ...

Numerical Investigation of Bubble‐induced Marangoni Convection [PDF]

Annals of the New York Academy of Sciences, 2009
The liquid motion induced by surface tension variation, termed the thermocapillary or Marangoni effect, and its contribution to boiling heat transfer has long been a very controversial issue. In the past this convection was not the subject of much attention because, under terrestrial conditions, it is superimposed by the strong buoyancy convection ...
