Journal ArticleDOI
Hole expansion from a bubble at a liquid surface
TL;DR: In this paper, the authors studied the expansion of the outer radius of the hole at the free surface, as well as its velocity of expansion (uo), for millimetre to micron sized bubbles, floating at free surface of different low viscosity fluids with different surface tensions.
Journal ArticleDOI
Dynamics of Collapse of Free Surface Bubbles
TL;DR: In this paper, the authors study the collapse of cavities formed by bubbles of different radius R at the free surface of five different fluids and show that the cavities collapse is dominated by surface tension and inertia with viscosity not playing a role.
Journal ArticleDOI
On separating plumes from boundary layers in turbulent convection
Prafulla P. Shevkar,R. Vishnu,Sanal K. Mohanan,Vipin Koothur,Manikandan Mathur,Baburaj A. Puthenveettil +5 more
TL;DR: In this paper , a simple kinematic criterion was proposed to separate line plumes from local boundary layers in a plane close to the hot plate in turbulent convection, based on the Lagrangian coherent structures (LCS) in the instantaneous limit.
Journal ArticleDOI
Inertial effects on the flow near a moving contact line
TL;DR: In this article, the authors quantify the effect of inertia on the velocity at the liquid interface and provide the leading-order inertial correction to the dynamic contact angles predicted by the classical Cox-Voinov model.
Journal ArticleDOI
Integral Analysis of Laminar Indirect Free Convection Boundary Layers with Weak Blowing for Schmidt No. ∼ 1
TL;DR: In this article, the effect of the blowing parameter on boundary layer thickness, velocity and concentration profiles is analyzed using an integral analysis, showing that strong blowing is seen to increase the wall shear stress.
