内容記述 | In this research, the ensemble Kalman filter, a data assimilation method, is employed to estimate the turbulent viscosity for the flow field around the RAE2822 airfoil. The turbulent viscosity is estimated directly from the experimental pressure distribution on the airfoil, without a turbulence model. The turbulent viscosity estimated by the ensemble Kalman filter shows lower magnitude around the airfoil than that estimated with the Spalart-Allmaras turbulence model and is almost zero in the wake region. Computation with the estimated turbulent viscosity can predict the separated flow region at the shock-boundary layer interaction. Due to this separation, the computed pressure coefficient agrees better with the experiment. These results suggest that this data assimilation method can be used to estimate the turbulent viscosity without a turbulence model. | |||||
