Abstract

Abstract

Numerical simulation is reported for the two-dimensional driven cavityflow with aspect ratio two. Calculation has been performed for Reyonld number from 100to 10000 on nonuniform staggered grids with the modified implicit Temam scheme andpressure correction method.When Re≤3000, steady-state solutions have been obtained;when Re≥3500, periodic asymptotic solutions have been obtained and verifed with spectralanalysis.It is shown that Hopf bifurcation occurs between Re = 3000 and 3500.
- driven rectangular cavity flow,
- modified implicit Temam scheme,
- periodicasymptotic solution
