Based on the mechanism of the cavitation effect in the self-excited oscillation pulsed jet nozzle, a modified cavitation model is proposed for improving the precision of the simulation, which considers the influence of Reynolds shear stress, the viscous shear stress and the turbulent pressure fluctuations existed in the shear layer on the vapor pressure. The modified cavitation model is hooked in...
Nonlinear fault diagnosis methods based on kernel function have great computation complexity for all training samples are introduced in model training. This paper proposes a novel nonlinear fault diagnosis method based on multiple sparse kernel classifiers (MSKC). In the proposed method, fault diagnosis is viewed as a nonlinear classification problem between normal data and fault data. Kernel trick...
