Below is a top-down view of an airflowanalysis of the same design on an A320, with the associated pressure contours for an unmodified and modified fairing.
以下是A320气动性能分析的俯视图。图5 a显示的是未经改装的整流罩上的压力分布图。

According to the analysis of field test results, the reasons of opposite direction airflow are found, and it is returned to normal airflow through taking appropriate measures.
The limitation of the Budryk's method(static analysis method), which ignores the effect of the length and the initial airflow rate of a parallel airway on airflow reversal, is pointed out.
