A NUMERICAL SCHEME FOR HYDRODYNAMIC LUBRICATION OF SYNOVIAL-FLUID

In recent years considerable attention is paid by researchers on the s tudies of human locomotion. Morrison(1) studied physiological models f or the evaluation of muscle forces, Hogan(2) studied the mechanics of multi-joint posture and movements, Bizzi et al.(3) studied the effect of load disturbances during movements and Hardt(4) studied the muscle forces in the leg during normal human walking In this paper the effect of thin film of synovial Newtonian fluid contained between slider bea rings, which consists of nearly two parallel plates of length L at ver y short distance h apart is studied. An interesting observation is tha t there are no large scale fluctuations in velocity along any normal c ross section of the lower plate. A critical Reynold number for the pro blem under consideration is found to be 600, beyond which the load is found to increase abnormally. This brings to light, one of the importa nt results for the rupture of joints.
