A schema of the problem is displayed in the file RBC_schema.eps. It addresses
a Rayleigh-Bénard convection (RBC) in an air filled rectangular cell of aspect
ratio unity and pi span-wise open-ended distance. The cell is heated from
below and cooled from above isothermally, while the sidewalls are adiabatics.
No-slip boundary conditions are imposed at all the four solid walls whereas
periodic boundaries are applied in the longitudinal span-wise direction.
By introducing the dynamical characteristic parameters of Ra={10^8,10^10}
and Pr=0.7 numbers, a turbulent flow is developed.
