Dielectric barrier injection (DBI) devices were shown to be reliable in flow control applications. Particle Image Velocimetry (PIV) techniques could be adapted in order to obtain velocity fields of the flow generated by DBI devices. In this work, the momentum integration method is applied on velocity fields obtained by PIV to estimate the electric force generated by a DBI actuator. A control volume surrounding the produced flow is carefully selected. The electric force is then computed. The influence of the electric signal frequency on the EHD force is studied. Finally, a time-resolved analysis is carried out to study the temporal behavior of the electric force during a complete electric signal cycle.
