Low Swirl Simulation

swirl=.07, viscosity=.0001.


This page shows the low swirl simulation in the comparison of 4 simulations. The intense vortices are single vortices capped by a spiral vortex breakdown.

Maxima in the lower half of the domain. w is vertical velocity, s is speed, q is of sqrt(-2p'/ρ).

Same as above, but showing only 45<t<65. Two animations are presented below, for 47<t<49, and 59<t<60.5, the time spans indicated with the yellow bars.
