A study was made of the physical processes taking place during the generation of a shock wave at the outlet of a nozzle of a gas-generator station, when emitted into the atmosphere at a supersonic velocity of the gas mixture formed in the chamber during the combustion of gas. The investigation of the spectral characteristics of an exciting shock sound wave was made as well as the corresponding computations of the height of the wave propagation dependences. The dependences of the intensities of obtained sound waves on the frequency were computed. The intensity levels of the action of sound waves on the clouds depending on the height of their location were determined. The obtained values of the surface energy densities of the excited sound waves at the heights of 500 m, 750 m, and 1000 m are equal to 0.258 J/m2, 0.115 J/m2, 0.064 J/m2, respectively, from which it follows that the influence of these waves on the hail clouds can be noticeable only at the altitudes of the order of 500 m.

煤气发生站激波产生过程中物理过程的研究

研究了在气体发生器站的喷嘴出口处以冲击波的形式发生的物理过程,当该气体以燃烧过程中在室内形成的气体混合物的超音速排放到大气中时,气。对激振声波的频谱特性进行了研究,并对波传播相关性的高度进行了相应的计算。计算获得的声波强度与频率的关系。确定了声波在云上的作用强度水平,具体取决于其位置的高度。在500 m,750 m和1000 m高度处获得的声波的表面能密度的值等于0.258 J / m 2,0.115焦耳/米2,0.064焦耳/米2,分别从其中它遵循这些波在冰雹云的影响只能在500微米量级的高度明显。
