    Abstract
  • The boundary layer entrainment mass flow of rotary disk was analyzed numerically in order to improve the performance of one-dimensional(1-D) flow model of rotor-stator cavity. The numerical results show that, 1/7 power law assumption of boundary layer velocity distribution underestimats the boundary layer entrainment mass flow of free disk, affecting the calculation of source region boundary position; the traditional correlations can not correlate the numerical results of boundary layer entrainment mass flow on rotary disk under different conditions well, affecting the calculation of swirl ratio in core region of 1-D flow model. Correlations of boundary layer entrainment mass flow on free disk and rotary disk in rotor-stator cavity were brought out by investigating the numerical results, and 1-D flow model was corrected accordingly. Moreover, the corrected 1-D flow model was verified by experiments, showing that the corrections improved the accuracy of 1-D flow model with respect to the radial pressure difference calculation.
