The rapidly advancing contact line Part-1: Navier slip and microscale inertial effects
Yash Kulkarni, Tomas Fullana, Stephane Popinet +1
Curtain coating, in which a moving plate is coated by a falling liquid sheet, sustains advancing contact lines at large capillary numbers Ca ~ O(1), based on plate speed. Steady st…
Scale- and Structure-Dependent Fractal Dimensions in a Two-Dimensional Atomizing Liquid Jet
Guangnian Ji, Yash Kulkarni, Stéphane Zaleski
Atomization stretches and folds the liquid-gas interface before fragmenting it into ligaments and droplets, making fractal measures a natural descriptor of the breakup state. We ex…
A consistent treatment of dynamic contact angles in the sharp-interface framework with the generalized Navier boundary condition
Tomas Fullana, Yash Kulkarni, Mathis Fricke +4
In this work, we revisit the Generalized Navier Boundary condition (GNBC) introduced by Qian et al.\ in the sharp interface Volume-of-Fluid context. We replace the singular uncompe…
The atomizing pulsed jet
Yash Kulkarni, Cesar Pairetti, Raphaël Villiers +2
Direct Numerical Simulations of the injection of a pulsed round liquid jet in a stagnant gas are performed in a series of runs of geometrically progressing resolution. The Reynolds…
