瞬时畸变极值预测的随机涡方法

摘要

An improved random vortex model for predicting maximum instantaneous pressure distortion is presented based on the statistical behavior of turbulence type dynamic inlet total field generated by plate type turbulence generator.A new statistical method is put forward for determining the vortex core size.The numerical results show good accuracy of the prediction.This method also decreases the dynamic inlet pressure measurements.The effectiveness of the method in decreasing both cost and time is proved well.
