    Samenvatting

    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 oi!. The main topic ofthe paper is the development of a numerical method for these equations, the deve10pment of a new Osher-type flux-difference splitting scheme. 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.
