Abstract
This paper reports on an investigation of the adequacy of computational fluid dynamics (CFD), using a stabilized finite element formulations to solve buoyancy-driven incompressible flows with heat and mass transfer, specifically to 3D applications. The finite element formulations are implemented in parallel using message passing interface (MPI) libraries. Parallel implementation assumes that the mesh is totally unstructured. To solve very large-scale applications, a matrix-free GMRES iterative solver is used to obtain the solution of nonlinear systems. The 3D application is the simulation of the carbon dioxide distribution within a Boeing 777-200 cabin. These results suggest that this modeling approach is adequate for predicting pollutant transport in an aircraft cabin.
