Rotordynamic coefficients derived. Report presents analysis of incompressible flow in annular turbopump seal with straight or radially/axially wavy (azimuthally symmetrical) surface facing shaft. Purpose of analysis to quantify effects of waviness on rotordynamic coefficients of seal. Whirl-frequency ratio of wavy rough seal considerably less than straight rough seal.
