摘要
对热力发动机中存在的线性声振荡燃烧的研究,通常假设速度耦合与压力耦合的作用独立无关且作用结果可以线性相加。本文通过对压力耦合与速度耦合现象的分析,说明了使这一假设不合理的平均流速界限,并给予了实验证明。
In analytical studies of some linear acoustic combustion in a motor, usually assumpts that the velocity coupling is independent of pressure coupling and the result can be repeatedly added. In this paper, a theoretical analysis with velocity coupling and pressure coupling has been obtained. It proved the usual assumption is incorrect in the quantity of mean flow velocity, the experimental results also give the verification of it.
