利用中瓷YE 6263压力数据采集系统对文氏管喉部和三角形多孔板后的压力特性进行了实验研究，分析了文氏管喉部长度、多孔板不同几何参数及其组合对时均压力、气穴数以及通过快速傅里叶变换计算的压力频谱、相关函数的影响。实验结果表明，L/R= 40的喉部长度有利于提高脉动能量，促进能量均匀分布，适当减小节流孔尺寸和增加节流孔数量可促进脉动能量在频域的均匀分布。在组合反应器中，多孔板后的空化数较低，关联函数波动较大。
The pressure characteristics in the throats of Venturi tube and behind triangular multi-orifice plates were experimentally investigated by a pressure data acquisition system of SINOCERA-YE6263, and the effect of throat length of Venturi tube, different geometric parameters of multi-orifice plate and their combinations on the time-averaged pressure, cavitation number, and pressure frequency spectrum, correlation function calculated by FFT were analyzed. The experimental results showed that the throat length ofL/R= 40 made for improving the fluctuation energy and promoting the uniform energy distribution, appropriately decreasing the size and increasing the number of orifice could accelerate the uniform distribution of the fluctuation energy in frequency domain. In the combination reactors, the cavitation number behind multi-orifice plates was lower and the fluctuation of correlation function was more intense.
