] investigated the formation of vortex rings in uniform background co-flow, and it is the opposite setting compared to the experiments of Dabiri and Gharib [8]. They measured vortex ring circulation and the formation time that it took for them to form during pinch-off process, for the co-...
VORTEX RINGSSTRATIFIED FLUIDSMIXINGA numerical study of the formation and transport of vortex rings in a cylindrical tank initially occupied by a thermally stratified fluid is presented. A control-volume based finite-difference technique (Patankar's SIMPLER method) is used. The formation of a vortex...
Based on the impulse law, it is speculated that the fluid force generated by the formation of the rear vortex rings can be enhanced. Therefore, the strong interaction between wake vortices can actually improve the propulsive efficiency of the biological systems by operating the formation of large-...
Three-dimensional instability of a plane free shear layer: an experimental study of the formation and evolution of streamwise vortices J. Fluid Mech. (1988) P Orlandi et al. Vortex rings impinging on walls: axisymmetric and three-dimensional simulations J. Fluid Mech. (1993) There are more ref...
It is concluded that whistling can be included in the same class of sound sources as the Rayleigh bird call and the Pfeifentne, since the essential mechanism for exciting them depends on the instability of a jet to the formation of vortex rings and the interaction of the rings with a rigid...
It is clear that following the formation of an inflection point (see Fig. 4c) that the Seifert frame, depicted by the yellow stripe, and the Frenet-Serret basis (green stripe) rotate in opposite direc- tions. Therefore, whereas one varies covariantly, the other varies contravariantly which...

grid (QSCT), to explain the formation of cancer cell at the fundamental quantum-physical level in order to make new insights into the internal relationship between the malignancy of various types of cancer cells and the fundamental physical law governing the process of cancer cell formation. Accor...
There, conservation of angular momentum carried by the cooled plasma results in the formation of vortex flows that extend from the low photosphere into the top layer of the convection zone. This effect is also known as bathtub effect (Nordlund 1985) as it reminds of the swirling motion of ...
