摘要
扰流插板引起的进气畸变流量随插板高度升高具有收敛到某一点的趋势。截面平均总压和周向低压区内平均总压与进气流量成线性关系。据此,可以预估周向畸变指数。低压区周向角只与插板高度成线性关系。截面稳态畸变压力分布可以分成高压区、掺混区、低压区,且分布各有特点,边界明显。
By an inserted board airflow inlet distortion test, the flow will be reduced to a point with raising the inserted board. The section average total pressure and the average total pressure in the circumferential low-pressure areas are in linear relationship with the air inlet flow. Then, the circumferential distortion exponent can be estimated. The circumferential angle in the low - pressure area just is in linear relationship to the inserted board height. The section steady distortion pressure distribution can be divided into high pressure area, mixing pressure area and low pressure area, each has its own characteristic in distortion and their boundaries are obvious.
