| 摘 要： | 本文分析比较了轴对称紊流发生器的主要几何参数对紊流度的影响.试验表明,采用适当的面积比,较小的扩张角和收缩比,较短的相对长度,在M_2=0.4～0.6的范围内,能获得较高的紊流度.如当M_2=0.5时,紊流度可达0.076,总压恢复系数为0.74.

| Abstract: | The paper describes the main geometric parameter effects on the turbulence for the axisymmetric type of turbulence generator. The experiments show that the higher turbulence is reached in M2 = 0.4-0.6 when the smaller divergence angle, smaller convergence ratio, smaller relative length and suitable area ratio are adopted. For example when M2 = 0.5 the turbulence equals 0.076 and the total pressure recovery efficiency 0.74. |
