Rayleigh-Bénard convection in a newtonian liquid bounded by rigid isothermal boundaries

作者:

Highlights:

• Pitchfork bifurcation in the case of rigid boundaries is reported.

• A new Fourier-Galerkin expansion is proposed for rigid boundaries.

• Chaotic, mildly chaotic and periodic motions are reported.

• Results of rigid boundaries are compared with those of free boundaries.
