... on impact pressure, which is obtained from the numerical simulation of a single spherical droplet impingement on a solid wall ( Ref 8 ). The numerical results are shown for the damping coefficient, η (= P wet / P dry ), with respect to the nondimensional liquid-film thickness, κ (= δ/ d ), where P wet...

... are incorporated in the bucket design to suppress resonant vibration. The bucket shank, which joints the airfoil and the dovetail, is a significant fraction of the overall bucket length. Damping is introduced near the bucket midspan by placing axial pins underneath the platform between adjacent buckets...

... that vermicular graphite damped the back-reflection signal to a significantly greater degree than nodular graphite did. Comparison of the results obtained in the ultrasonic tests and in the metallographic examinations yielded a correlation coefficient of 0.84–an indication of a high degree of correlation...
