Large eddy simulation of Rayleigh-Benard convection using truncated Navier-Stokes equation

Using concepts from the subgrid-scale estimation modeling we develop a procedure for large eddy simulations which employs Navier-Stokes equations truncated to an available mesh resolution. Operationally the procedure consists of numerically solving the truncated Navier-Stokes equation and a periodic processing of the small scale component of its solution. The modeling procedure is applied to simulate turbulent Rayleigh-Benard convection.
