Abstract
In asymmetric blowing of a gas into the supersonic part of a nozzle the main flow is perturbed by the jet which is being blown. Two interaction regimes are distinguished. In the first the perturbation of the main flow does not extend to the side of the nozzle opposite to the blast: the central angle subtended by the perturbation of the exit section of the nozzle is 2γa < 180 ° (Fig. 1). This regime is characterized by the fact that the curvature of the nozzle has no effect on the magnitude of the lateral force. In the second regime the zone of the perturbed flow extends to the side of the nozzle opposite to the blast (2γa > 180 °), and this leads to a decrease in the gradient of the lateral force with respect to the flow rate of the gas which is being blown. The first regime has been studied in the most detail.
