We show that laminar vortex rings can be generated by impulsive body forces having particular spatial and temporal characteristics. Numerical simulations analytical models the strength of these accurately predicted considering diffusion alone, despite nonlinear nature generation process. It is found when duration force less than a time scale based on radius fluid viscosity, ring circulation using an inviscid model.
It is shown that laminar vortex rings can be generated by impulsive body forces having particular spatial and temporal characteristics. The method produces in a fluid initially at rest, once generated, the flow field automatically satisfies boundary conditions divergence-free. Numerical simulations analytical models show strength of these accurately predicted considering diffusion alone, despite nonlinear nature generation process. A particularly simple model, which approximates source...
