Abstract Turbulent convective flow of water in horizontal layer with free and rigid horizontal boundaries, arising at heating from below, is numerically simulated using the Boussinesq model without any semiempirical relationships (DNS) in 2-D case. It is shown that numerical results (free) have good agreement with experimental data and results of numerical simulations with rigid boundary conditions at enough high supercriticality and that such simulation reflects the transition to hard turbulence. We study also the role of boundary conditions (free-rigid).
