Shankar, PN (1995) Low Reynolds number piston generated toroidal vortices. In: 6th Asian Congress of Fluid Mechanics, 22-26 May 1995, Singapore.Full text not available from this repository.
A theoretical analysis is presented of the low Reynolds number flow generated by the efflux of fluid through an orifice due to the impulsive motion of a piston. The paper presents a complete solution of the linearized Navier-Stokes equations that govern the flow field. The solution shows that the resulting toroidal vortices, quite unlike their high Reynolds number counterparts, are generated at the rear of the slug and move principally by diffusion. For unit slug length the vortex center moves linearly at approximately 48 deg to the vortex axis.
