Simulation of the Start-Up of a Turbulent Free Convection Driven by Wall Heating and Cooling
Original language description
This paper presents first free results of a newly developed numerical model aimed to address the problem of a free and forced convection in atmospheric boundary layer flows over a complex terrain. The problem chosen for this initial study describes a flow in a simple two-dimensional V-shaped valley. The flow is generated by heating/cooling valley walls which results in free convection circulation. Different wall temperatures and background stratification rates are considered. The equations of fluid motion are based on the Boussinesq approximation of momentum equations, supplemented by the divergence free incomperssibility constraint. Turbulence is described by a modified SSTk-omega model.
