    Abstract

    To predict high-frequency oil-flow phenomena in hydraulic-shock-absorber designs, a mathematical-physical model is proposed. The model consists of the 2-D unsteady Euler equations in axial-symmetric coordinates and an appropriate equation of state for oil. The main topic of the paper is the development of a numerical method for these equations. A new Osher-type flux-difference splitting scheme is derived for it. The mathematical-physical model and its numerical approximation are applied to a simplified part from a shock-absorber design. The method is promising as far as more realistic computations are concerned.
