Аннотация:EDN: HQKEHV The effect of taking into account stream swirl when calculating the flow of a subsonic air plasma jet past a cylindrical model of 50 mm in diameter when the jet flows out from the discharge channel into the test chamber of the VGU-4 IPMech RAS HF plasmatron is studied. A comparison has been made of calculations of axisymmetric flow past the model based on the full Navier–Stokes equations taking into account (new results) and without taking into account (old results) the tangential velocity component w under the experimental conditions at a pressure of 80 mbar in a wide range of anode supply power at various distances from the plasmatron channel outlet to the model.
