The app calculates the stiffness, damping and mass from flow through annular clearances on rotating equipment including pumps and compressors.

The coefficients calculated from this app can the. be used in the cross coupled stiffness matrix (not included) to allow further claculation of shaft deflections and damped critical speeds.

The values are calculated using the methods presented by Black and Jennson
