AN INVESTIGATION OF A SQUEEZE FILM BETWEEN 2 PLANE ANNULI

An analysis of a laminar squeeze flow of art incompressible Newtonian fluid between parallel plane annuli is presented. The local and convec tive inertia of the flow are considered in the investigation. The solu tion is obtained as a power series in a single nondimensional paramete r (squeeze Reynolds number) S, for small values of S. Expressions for the pressure and load capacity are given and are compared with those b ased on the assumption of inertialess flow As applications, the consta nt velocity squeezing state and the case when the walls perform recipr ocating harmonic oscillations with finite amplitude are considered. Th e changes in load capacity with the changes in the parameters that gov ern the motion have been investigated.
