The effect of convection on the position of the free liquid surface under zero and terrestrial gravity

TL;DR

This paper uses numerical modeling to study how convection affects the position of the free liquid surface in an air-water system under different gravity conditions, considering thermocapillary and gravitational effects.

Contribution

It introduces a numerical approach to analyze the impact of convection on interface deformation and position in a two-layer air-water system under lateral heating.

Findings

Convection influences the deformation of the free surface.

Gravity and thermocapillary effects alter the interface position.

Results vary under zero and terrestrial gravity conditions.

Abstract

Theresults of numerical modelinghas based on the solution of Navier-Stokes equations for convection oftwo-layer system air-water are presented.The influence of thermocapillary and gravitational convection on the deformation and time averaged position of the interface of air-water system under sudden lateral heating of a square-section cavity are shown.
