研究了用VITA条件采样方法检测壁湍流猝发的门限值与壁湍流猝发平均周期之间的关系 ,根据用壁湍流流向脉动速度自相关函数检测得到的壁湍流猝发平均周期 ,确定壁湍流猝发VITA条件采样的门限值K。
The relationship between the threshold of wall turbulent burst detection and the average period of wall turbulent burst detection by VITA condition sampling method was studied. According to the average period of wall turbulent burst detected by wall turbulence self-correlation function, the turbulence burst VITA Threshold value for conditional sampling.
