Bone and cartilage co-operate in human joint. The gap between their surfaces is filled with synovial fluid. In this case, the solution of the lubrication problem should be based on actual, various geometry of co-operating surfaces of human joint. In this paper we consider a symmetrical flow of synovial fluid between spherical, hyperbolic and parabolic bone surfaces in human joint. In order to study the symmetrical flow of synovial fluid in joint gap, we obtain velocity components and hydrodynamic pressure distributions in final, dimensionless form.
