| Summary: | A successive approximation linearizes the partial Analyses for incompressible and compressible spiral groove and a Finite Element Method (FEM analysis validate the both the incompressible and compressible fluid cases. compressible fluid analysis. The zeroth- and first-order compressible fluid SGFS geometry follows from a parametric differential equation of pressure that arises in the equations giving the static and dynamic performance of SGFSS, Favorable comparisons with the Narrow Groove Theory (NG7-) flow. A parametric study indicates effects of changing face geometry. Validation of the isothermal compressible fluid incompressible fluid case for SGTBs without inward radial leakage rate, and power loss and gives the optimum SGFS lubricated seal rings. model occurs by comparison of the static and dynamic SGTB and respectively, are solved using the finite element method for seal geometry on the opening force, force coefficients, SGFS behavior with previous NGT analyses. The optimum study, indicating the advantages of using grooved face seals thrust bearings (SGTBS) and face seals (SGFSS) are presented. with seal dams over traditional mechanical face seals and oil |
