This paper presents numerical simulations of high lift flow using the code HiFUN. The configurations NASA Trap Wing and DLR F11 considered for the analysis are candidate configurations employed in AIAA high lift prediction workshops 1 and 2 respectively. Unsteady time accurate simulation is performed for NASA Trap wing configuration in order to assess predictive capability of RANS based tools like HiFUN to capture experimentally observed hysteresis in lower leg of the lift curve. A number of steady RANS computations are performed for DLR F11 configuration to carry out grid convergence study, understand effects of simulating support brackets and pressure tube bundles on numerical predictions and understand predictability of Reynolds number effect. Most of these calculations have been carried out using standard Spalart Allmaras turbulence model. In addition, few calculations have been performed using more popular standard k - ω SST turbulence model and lesser known k - ω TNT turbulence model with an objective of understanding their relative merits in simulating high lift flow for DLR F11 configuration.
