Liquid Transfer for Viscoelastic Solutions
Hrishikesh Pingulkar, Jorge Peixinho, Olivier Crumeyrolle
Viscoelastic liquid transfer from one surface to another is a process that finds applications in many technologies, primarily in printing. Here, cylindrical shaped capillary bridge…
Flow and air-entrainment around partially submerged vertical cylinders
Valentin Ageorges, Jorge Peixinho, Gaële Perret
In this study, a partially submerged vertical cylinder is moved at constant velocity through water, which is initially at rest. During the motion, the wake behind the cylinder indu…
Features of Transition to Turbulence in Sudden Expansion Pipe Flows
Minh Quan Nguyen, Benoit Lebon, Mostafa Safdari Shadloo +2
The complex flow features resulting from the laminar-turbulent transition (LTT) in a sudden expansion pipe flow, with expansion ratio of 1:2 subjected to an inlet vortex perturbati…
Flow in a Circular Expansion Pipe Flow: Effect of a Vortex Perturbation on Localized Turbulence
Kamal Selvam, Jorge Peixinho, Ashley P. Willis
We report the results of three-dimensional direct numerical simulations for incompressible viscous fluid in a circular pipe flow with a sudden expansion. At the inlet, a parabolic…
Effect of the number of vortices on the torque scaling in Taylor-Couette flow
B. Martínez-Arias, J. Peixinho, O. Crumeyrolle +1
Torque measurements in Taylor-Couette flow, with large radius ratio and large aspect ratio, over a range of velocities up to a Reynolds number of 24 000 are presented. Following a…
Transition to turbulence in slowly divergent pipe flow
Jorge Peixinho, Hugues Besnard
The results of a combined experimental and numerical study of the flow in slowly diverging pipes are presented. Interestingly, an axisymmetric conical recirculation cell has been o…
