辛辛那提大学（UC）建造了一台新的吸气式乙烯脉冲爆震发动机（PDE）装置。该设施支持多达六个两英寸或三英寸的爆震管，由汽车衍生的阀门和点火系统以及用于爆燃转爆震的Shchelkin型螺旋驱动。新PDE还与轴流动力涡轮机匹配，每个PDE管提供涡轮机入口的六分之一扇区，以便可以在PDE经受的部分进气和脉冲流或爆震流下研究涡轮机效率。每个PDE和其进气扇之间的接口紧密耦合，以最大限度地提高脉动和部分进气的效果。本文记录了这一新设施的具体细节，提供了一些有代表性的情况下的样本数据，并提供了足够的信息系统的几何形状和初始条件，以支持其操作的数值模拟。所提供的样本数据应允许验证这些数值模拟。
A new air-breathing ethylene-burning Pulse Detonation Engine (PDE) facility has been constructed at the University of Cincinnati (UC). This facility supports up to six twoinch or three-inch detonation tubes driven by an automotive-derived valving and ignition system and Shchelkin-type spirals for deflagration to detonation transition (DDT). The new PDE is also mated to an axial-flow power turbine with each PDE tube supplying a one-sixth sector of the turbine inlet so that turbine efficiency may be studied under the partial admission and pulsing flow or detonating flow that the PDEs subject it to. The interface between each PDE and its inlet sector is closely coupled in order to maximize the effects of pulsation and partial admission. This paper documents the particular details of this new facility, provides sample data for a few representative cases and provides enough information on the system’s geometry and initial conditions to support numerical simulation of its operation. The presented sample data should allow validation of these numerical simulations.
