- •
Double-diffusive Rayleigh–Bénard flow in a cylindrical enclosure is simulated.
- •
The critical Rayleigh number at the primary threshold is determined.
- •
Flow pattern transition and bifurcation sequences are exhibited.
- •
The effect of the buoyancy ratio on the flow instability is confirmed.
