Dielectric barrier discharge actuators are promising candidates for supersonic boundary-layer transition control because of their ability to concentrate energy transfer in receptive regions in the depth of the boundary layer. A detailed understanding of the plasma–flow coupling mechanisms and optimum scaling in compressible flows is necessary to develop efficient actuation schemes. In this work, the dielectric barrier discharge momentum transfer to an unstable laminar boundary layer over a flat plate under different Reynolds and freestream Mach numbers is studied. A new coupled plasma–compressible flow solver using a block-structured adaptive mesh refinement algorithm is presented, which was developed to model the force field generated by the actuator. The spectral components of the force are used as source terms for the study of the influence of flow conditions and length scales on linear receptivity.
