Modifications to a two-control-volume, frequency dependent, transfer-function analysis of hole-pattern gas annular seals
Abstract
A rotordynamic analysis of hole-pattern gas annular seals using a two-control-volume model, Ha and Childs and frequency dependent transfer-function model, Kleynhans and Childs is modified with four features. The energy equation is added, and real gas properties are used instead of the ideal gas equation of state. The depth of the hole-pattern is made variable with the axial distance along the seal. And last, the addition of deep grooves to hole-pattern seals is analyzed, and the codeâÂÂs predictions for the influence of a groove are compared with test data.
