Figures

Grahic Jump Location
Schematic illustration of a machine turned static ring gasket
Grahic Jump Location
Schematic illustration of the crest and valley height fluctuations
Grahic Jump Location
Model static ring gasket. The ring width Δr is grossly exaggerated for clarity. The thin inner solid line shows the spiral crest. The inner dashed line shows the bottom of the spiral valley. The local slopes are also exaggerated (in fact a/λ≪1).
Grahic Jump Location
For ε<0, a simple geometric erosion rule is used as depicted in the figure
Grahic Jump Location
Radial and circumferential fluxes as a function of ε. (a) diffusive fluxes, (b) viscous fluxes.
Grahic Jump Location
Total flux (radial+circumferential) as a function of ε. (a) diffusive flux, (b) viscous flux.
Grahic Jump Location
Evolution of K*/D* as a function of ε
Grahic Jump Location
Schematic view of the model ring gasket with error of form on the top surface. Dimensions within the ring as well as local slopes are grossly exaggerated for clarity.
Grahic Jump Location
“Unrolled” view of contact area (in black) and aperture field for the system with error of form. Constrictions along the circumferential and radial paths are shown. For ε<−2α, only a circumferential leak is possible as shown in εcd (b).
Grahic Jump Location
Influence of an error of form on the flow rate through the ring gasket. A is the contact surface fraction. Qef is the flux with error of form. Q is the flux without error of form for the same contact surface fraction.
