- •
A micro plasma actuator was experimentally characterized and numerically modelled.
- •
Three different approaches of modelling the plasma-induced body force were tested.
- •
The Dual Potential Model, calibrated on experimental forces, was the best approach.
- •
The downstream decay of the wall-jet velocity was successfully predicted.
- •
A maximum velocity of about 2 m/s was obtained and a jet thickness of about 3 mm.
