A numerical simulation is conducted to investigate the characteristics of weak flow generated by array slots jets in a high-speed crossflow. The jet to crossflow velocity ratio is 0.055 and the crossflow velocity is 100m/s. Flow field and pressure drop performances are compared between the jet with and without array slots. The results show that the counter-rotating secondary vortex from the jet with array slots is more clearly induced by the jet-to-crossflow interaction than that without array
