“…To the best of the authors' knowledge, no work in the literature has extensively focused on the interaction of highly unsteady pulsed jets with small surfaces of high degree of curvature and its impact on the pressure drag generation problem for bluff blunt bodies. Recently, several studies, for instance Berk, Medjoun & Ganapathisubramani (2017) and Stella et al (2018), have focused on the fine-scale dynamic interaction between pulsed or synthetic jets and recirculating wake flows such as backward-facing steps in order to draw general scaling laws involving the formation of the pulsed jets and its influence on the recirculating wake.…”
