AI Technical Summary
Traditional cavity pressure testing methods fail to effectively constrain the location of pressure measurement points, resulting in large uncertainties in pressure measurement and affecting the accuracy of axial force calculation.
The axial force on the rotor wall and the geometric dimensions of the rotating disk cavity are determined by three-dimensional numerical simulation. The axial projected area is calculated, the characteristic pressure value of the disk cavity is extracted, and the location of the cavity pressure measurement point is determined. CFX is used for flow field simulation and isosurface analysis, and a distance threshold is set to determine the location of the measurement point.
This improves the accuracy of the cavity pressure measurement point location and the reliability of axial force calculation, ensuring the accuracy of pressure measurement and enhancing the precision of axial force conversion.
