Development of the KHI in the out-of-plane velocity uz at t = 2, 6, and 10 for both viscosity models. The isotropic results have been multiplied by as much as 1000 in order to compare them to the switching results. In the switching case, the KHI appears initially along the diagonals before extending azimuthally. In the isotropic case, there is no evidence of the instability.
