“…The main contributors to this work are Mulcahy (1980), Haslinger et al (1990), Esmonde et al (1992) and Lu & Rogers (1992, 1995.…”

Nonlinear Fluid Forces in Cylindrical Squeeze Films. Part Ii: Finite Length

“…The studies of squeeze-"lm e!ects in heat exchangers by Mulcahy (1980), Haslinger et al (1990) and many others have shown the requirements of this kind of study and also revealed that, without the aid of some approximations, even the existing models are impossible to solve for some speci"c motions. Lu & Rogers (1994) used side-leakage factors to obtain "nite-length squeeze-"lm forces from an in"nitely long model for radial motions.…”

“…Recent experimental studies of cylindrical squeeze "lms with water are given by Rogers et al (1990), Haslinger et al (1990), Yu & Rogers (1991) and Lu & Rogers (1994, 1995. In Lu & Rogers (1994), the normal instantaneous squeeze-"lm force for a "nite length cylinder was measured for a cylinder with radial motions with zero or nonzero initial eccentricity.…”
