| Summary: | alloys which can deform easily under the high pressures that analysis compares wen with those of earlier researchers for and bearings. The focus of this research effort is to annular seals in the SSME-HPOTP are made up of soft Silver are usually encountered. This study analyzes the effects of are utilized to model the flow field while Moody's friction characteristics of these pumps depend significantly on the circumferential momentum and the energy transport equations develop a comprehensive thermo-elasto-hydrodynamic analysis eccentric seal analysis is based on the work of Nelson and eccentricity has been included for rigid seals. The effects of annular seals on the pump rotordynamics. Seal Engine Turbopumps (SSME-HPOTP and HPFTP) are prone to experience severe vibration problems due to high operating factor model is adapted to account for the wall shear flexibility on the dynamic characteristics of concentric High performance turbomachines such as the Space Shuttle Main high pressures and low clearances. Linings of interstage impact rotordynamic coefficients of the turbopumps due to namely the cubic spline interpolation method, is adapted to Nguyen (1988), but a much simpler and effective method, obtain the circumferential derivatives of the primitive of turbulent liquid annular seals and to understand the parametric, axi-symmetric Finite Element formulation of the pressures and speeds. The stability and response rotordynamic features of hardware elements such as the seals seal wall. Numerical solution obtained by the current seals. The wall deformations are obtained using an iso- stresses. Wall flexibility of the seal can significantly the rigid as well as the flexible cases. variables. The bulk flow continuity, axial and |
