The flow past a backward-facing step and the interaction of a synthetic jet with a duct cross-flow were investigated numerically using an incompressible RANS solver. The numerical result was able to predict the correct flow structure and velocity field for the backward-facing step. The synthetic jet actuator had a cylindrical cavity and the diaphragm movement was modelled physically accurate. The synthetic jet simulated was first validated with experimental data in quiescent flow, the jet velocity profile at peak phases were modelled correctly and net positive momentum was observed in the external region, while the actuator remained net-zero mass flux. The synthetic jet was then integrated into a duct to create a cross-flow, three different blowing ratios were simulated by adjusting the diaphragm vibration amplitude. The simulations allowed the formation of the synthetic jet to be analysed in a low Reynolds number cross-flow and demonstrated that URANS can be used to simulate synthetic-jet in both quiescent and cross-flow.
