摘要
本文叙述了一种通过探测高温两相流中热粒子的热辐射来测量粒子速度的热发射测速技术,该技术曾多次用于测量电弧加热器射流和火箭弹尾喷火焰中的粒子速度,取得了比较满意的结果。
A thermal emission velocimeter(TEV)technique to mea-sure particle velocity was discussed.The principle of the techniqueis the detection of thermal radiation from the hot particle in hightemprature two-phase flow.The technique used to measure particlevelocity in arc-heater jet and rocket shell spurt flames,to get moresatisfied results.
