摘要
选择等截面二元长直管超音速扩压器,主要考虑是这种型式的扩压器性能对入口条件的改变比较稳定。基于这种扩压器流场的阴影图分析,本文提出了计算扩压器流场的简化模型,得出了设计计算的相应方程和方法。给出了两个算例。计算结果与相应的实验结果比较表明,本法可实际用于超音速气动激光器扩压器的初步设计。
Due to:its stability with respect to variations of inlet conditions,two-dimensional Long constant-area supersonic diffuser is selected for discussion and analys-is.Based on the analysis of shadowgraph observation,a simplified model for calculatingdiffuser flow field is provided,and the corresponding corresponding equations and method for designcalculation are formulated.Two numerical examples are given.The comparison be-tween these calculated results and the related experimental results appnars to show thatthe present design algorithm based on the simplified model is practically applicable toconceptual design of diffuser for supersonic gasdynamic lasers.
