摘要:
The stability of the axisymmetric Burgers vortex solution of the Navier–Stokes equations to two‐dimensional perturbations is studied numerically up to Reynolds numbers,R=&Ggr;/2&pgr;&ngr;, of order 104. No unstable eigenmodes for azimuthal mode numbersn=1,..., 10 are found in this range of Reynolds numbers. Increasing the Reynolds number has a stabilizing effect on the vortex. ©1995 American Institute of Physics.
