| in support of defogging studies of automotive vehicles, a 2D steady state numerical simulation and phase change modeling for a developing wall jet experimental facility were performed with a commercially available CFD code, FLUENT.; The velocity, temperature, and turbulence fluctuations were predicted with the standard k-ϵ, the realizable k-ϵ, and the Reynolds stress turbulence models. The simulation results were compared to experimental measurements after they were outer and inner scaled. The numerical predictions are in good agreement with the experimental data in outer scaling for isothermal and non-isothermal simulations without phase change.; Two phase change models were developed to perform the mass transfer simulation. The surface phase model was implemented, and gives promising water vapor condensation predictions in comparison with experimental drip-off tests. The volumetric phase change model is analytically established, and needs future work on implementation. |
