楔顶双孔压力受感器可以用来获取三维动态流场数据。本文分别采用三次样条插值、最小二乘法拟合和线性插值等三种方法,对基于楔顶双孔高频压力受感器试验数据进行了分析研究,结果表明线性插值法较样条插值、最小二乘法具有更高的精度。
Wedge double-bore pressure sensors can be used to obtain 3D dynamic flow field data. In this paper, cubic spline interpolation, least-square fitting and linear interpolation were used to analyze the experimental data of double-hole high-pressure sensor based on wedge top. The results show that the linear interpolation method is more effective than spline interpolation, Least square method with higher accuracy.
