NUMERICAL SIMULATION OF INTERACTION PROCESS BETWEEN DIELECTRIC BARRIER DISCHARGE AND DUCT FLOW
Numerical procedure of DBD modeling based on RANS equations has been developed and tested in present study both for the standard DBD and DBD working in constricted mode. Qualitative and approximate quantitative correspondence between known experimental data and numerical results has been achieved. Typical volume force and heat magnitudes has been evaluated, these values could be used as estimation in steady approximation calculations. Both DBD actuators models has shown up that required volume force magnitude has to be increased by 2 3 orders influence on flow separation in S type engine ducts at relatively high inlet velocity Different method of volume force calculation using actuator electrical parameters (DPM) has been carried out. Continuous volume force components fields have been calculated as a function of DBD actuator potential difference and charge density amplitude.
