Characterization of the Suction-and-Oscillatory-Blowing actuator by the hybrid RANS-LES CFD
Original language description
CFD simulations of the AFC effect are usually highly time consuming and require extensive computational resources and effort. These aspects almost exclude the simulation of the actuator arrays and the application of AFC during the design process. In this paper we study highly unsteady internal flow inside of the Suction and Oscillatory Blowing (SaOB) actuator in still air condition with the unsteady CFD simulations. The SST-DDES hybrid RANS-LES turbulence model is applied to verify previous results obtained with the aid of the URANS approach with k-o type turbulence modeling. The time dependent data obtained from these simulations were used for the development of simplified surface boundary conditions in order to simulate the SaOB effect on the flow-field in various applications. The goal is to verify the results of the less demanding URANS simulations and to provide better insight into the SaOB actuator internal flow.
