Wake dynamics of a square cylinder while moving upward in quiescent water
Intesaaf Ashraf, Stephane Dorbolo, Neetu Tiwari
We experimentally investigate the wake dynamics of a square cylinder rising through quiescent water over a range of Froude numbers (). Time-resolved Particle Image Vel…
Experimental investigation of the water exit of the accelerating circular cylinder
Intesaaf Ashraf, Stephane Dorbolo
We investigate the vortical dynamics generated during the forced exit of a circular cylinder through a quiescent free surface. While previous work on exit flows has largely emphasi…
Experimental investigation of exit dynamics of a circular cylinder out of water and silicone oil
Intesaaf Ashraf, Lionel Vincent, Romain Falla +3
Experimental investigations of the exit dynamics of a horizontal cylindrical object were performed in water and silicone oil (50 cSt). The fully immersed cylinder was initially at…
Exit Dynamics of a Square Cylinder
Intesaaf Ashraf, Stephane Dorbolo
In this paper, we experimentally investigate the exit dynamics of a square cylinder, that is initially fully immersed in a water tank and that crosses the interface perpendicularly…
Effect of the Surface Dimples on the Exit Dynamics of a Sphere at a Constant Velocity
Intesaaf Ashraf, Stephane Dorbolo
This article experimentally investigates the exit dynamics of two different spheres i.e. a smooth sphere and a sphere with dimples at a constant speed. Employing high-speed experim…
