Abstract
Lattice Boltzmann (LB) method is considered versus classical discretisation approaches to solve the problem of heat and fluid flow. The work considers situations with symmetry breaking for low Prandtl number fluids flowing in enclosures interesting directional solidification industry. The computed results demonstrate a good LB method's ability to captivate flow bifurcation thresholds. Particularly cavities exhibiting bifurcation sequences are considered and results are consistent with prior observations.
