Abstract: | The âMach boxâ method, based on the theory of sources distribution, has imposed as convenient in the study of nonstationary supersonic flows. The disadvantage of this method consist in the fact that for the numeric values of nonstationary potential and of pressure coefficient fluctuation of the results are registered caused by the shearing of the portent surfaces in rectangular network with finite area elements. In this paper is presented a method which lead to considerably elimination of these fluctuations and the classic method is optimized. |
