摘要

为了研究加速/减速过程中超声速进气道的起动/不起动现象

对二元超声速进气道的二维流场进行了定常/非定常数值模拟.分析了在来流马赫数为1.75~2.05范围内4种不同加速度绝对值对进气道气动性能的影响

并对定常/非定常模拟方法的结果进行了对比.结果表明:与定常模拟时相比

非定常数值模拟时进气道的流场特征在加速起动过程中和减速不起动过程中均存在明显的滞后现象

且加速度绝对值越大

滞后现象越明显;非定常模拟时的进气道处于起动状态时

其气动性能存在迟滞现象;当加速度绝对值一定时

进气道起动过程耗费的时间大于不起动过程耗费的时间.

Abstract

In order to study start/unstart flow characteristic in the acceleration/deceleration process

an investigation of two-dimensional mixed-compression supersonic inlet was performed in steady/unsteady numerical simulation. The effect of absolute value of acceleration on inlet performance was analyzed at Mach number from 1.75 to 2.05 and four different absolute values of acceleration were considered. The results of steady and unsteady numerical simulations were compared. The results indicate: in both start and unstart processes

the flow characteristic of the unsteady case lags behind compared with the steady one's

and the larger absolute value of acceleration means more obvious phenomena. The performance in unsteady simulation obviously lags behind that in steady simulation. The start process of inlet spends more time than unstart process under the same absolute value of acceleration.
