摘要

在一台内径61 mm、长度1140 mm的气动阀式脉冲爆震发动机(PDE)上

进行了爆震管热负荷的测量计算

主要采用了两种换热模型:一是自然对流和热辐射模型;二是强迫对流模型.在两种方式下

爆震管的热负荷随频率的变化关系基本相同

即随频率升高而热负荷增大

但频率增加两倍热负荷增加却不止两倍.此外

在方式二的情况下

还得到煤油蒸发率随频率的变化关系

为PDE蒸发器设计提供参考.

Abstract

A pulse detonation engine(PDE) with diameter and length of 61mm and 1140mm respectively

was used to get the heat loads of detonation tubes which were designed into two types.The first one is that its heat transfer was controlled by natural convection and thermal radiation

and the other one was mainly influenced by forced convection.The same relations between heat load and working frequency were acquired in two conditions

namely

the heat load increased along with the increase of working frequency.However

with the doubling of the frequency from 20Hz to 40Hz(or from 25Hz to 50Hz) of the detonation tube

the heat load increased more than 100%.In addition

the vaporizing rate of kerosene was got at different frequencies

providing a reference for the design of PDE evaporator.
