| 摘 要： | 介绍了八丝热线探针的制作工艺,有效地消除了各热丝探头之间的电信号干扰和动力学干扰。实验中使用该探针检测到了湍流边界层内的大尺度旋涡,并测量了它们的强度和尺度。与此同时还获得了速度、湍流强度和功率谱等流场参数,结果与现有典型数据一致。说明本文所述的多丝热线探针具有很强的实用性。

| Abstract: | The paper discribes the craft of making the 8-wire probewhich efficiently elimilates the electrical interference and dynamic dis-turbance between the sensors.The large eddies in turbulent boundarylayers have been detected and measured both in intensity and in scales.Simultaneously,the parameters in the flow field,including velocity,turbulence intensity and power spectra etc.,are obtained.The dataacquired from the 8-wire probe match the existed results well,whichindicates the practicality of the probe. |
