Abstract

ddcon2d solves the two-dimensional Navier-Stokes equations for Boussinesq convection by Fourier Galerkin + Collocation method. The system models double-diffusive convection in which two agents (e.g. heat and a solute) have opposing contributions to the bouyancy and diffuse at different rates. The problem is of relevance to oceans (heat + salt) and mixing in stars (heat + angular momentum, heat + concentrations etc.) It has been studied extensively in the laboratory, under different guises. The current set-up models the occurence of various waves (standing and traveling convection waves)
