TLDR
In this article, an approximate iterative solution of the continuity and momentum equations is derived for the instantaneous distribution of velocity within the fluid and the reaction on the surfaces of parallel surfaces, and the results obtained should be of interest in connection with the study of the performance of transiently loaded bearings in reciprocating engines.Abstract:
The problem of the squeezing of a film of liquid between two parallel surfaces is considered. Approximate expressions are deduced for the instantaneous distribution of velocity within the fluid and the reaction on the surfaces. These are obtained by an approximate iterative solution of the continuity and momentum equations. The radial pressure distribution in a squeezed film is found to be due partly to the action of viscosity and partly to inertia effects. The latter cause the relationship between the reaction on the surfaces and their relative velocity to be non-linear. This effect is significant for conditions where the Reynolds number based upon the distance between the surfaces and their relative velocity is greater than unity. The results obtained should be of interest in connection with the study of the performance of transiently loaded bearings in reciprocating engines, and a possible application in the field of chemical engineering might arise in connection with the phenomenon of adhesion.read more

Cavitation in Sudden Gap Expansion as a Model for Synovial Joint Cavitation
TL;DR: In this paper, the Stefan-Reynolds equation and Kuzma's derivation were used to model cavitation between axisymmetric parallel disks in an infinite domain, and analytical solutions for flow and pressure distributions were found using these simplified models.

An In-Line Reusable Launch Vehicle Concept Using Confined Load-Bearing Frozen Propellants
TL;DR: In this paper, the authors investigated a novel concept towards more affordable launch vehicles and is primarily theoretical along with development of computational analyses, which involves the storage of propellant as a frozen monolithic mass, phase change to fluid during flight and fluid delivery to a rocket engine; i.e., solid storage/fluid delivery (SSFD).

Inertia effects in viscous flows
TL;DR: In this paper, a method for including the inertia effects by solving the equation of motion approximately, in its integral form, is demonstrated with reference to the particular problem of radial flow between parallel plates.
