世界上第一台350 Hz热声驱动孔板脉冲管制冷机（TADOPTR）由泰克公司与洛斯阿拉莫斯国家实验室（LANL）和美国国家标准与技术研究所（NIST）合作设计和制造。这个高度仪表化的系统包括热线风速计和压力传感器，用于测量TADOPTR中所有关键位置的质量流量和压力的相位，首次允许与LANL和NIST开发的分析模型进行详细比较。速度、压力相、压力幅值和焓流的表征结果与模拟结果吻合较好。我们还展示了一种新的设计方法，该方法利用脉冲管在350 Hz处的惰性来实现质量流量和压力之间的所需相位，而不是通常的双入口设计。我们设计并表征了单级和两级350 Hz TADOPTRs。
The world’s first 350 Hz thermoacoustic driven orifice pulse tube refrigerator (TADOPTR) has been designed and built by Tektronix, Inc., in cooperation with Los Alamos National Laboratories (LANL) and the National Institute of Standards and Technology (NIST). This highly instrumented system includes hot wire anemometers and pressure sensors for measuring the phase of the mass flow and pressure at all key locations in the TADOPTR, permitting for the first time detailed comparison to analytical models developed by LANL and NIST. Characterization results for velocity and pressure phase, pressure amplitude, and enthalpy flow show good agreement with the simulations. We have also demonstrated a new design method that uses the inertance of the pulse tube at 350 Hz to achieve the desired phase between the mass flow and pressure, rather than the usual double inlet design. We have designed and characterized single stage and two stage 350 Hz TADOPTRs.
