Simplified model equations are proposed for simulations of propagation of weak shock waves in nonuniform liquid. It is explained why the equations can predict shock propagation in medium with arbitary distributions of the density and the acoustic speed which are given as parameters. The TVD scheme is applied to numerically solve the equations. Algorithms are shown for finite difference calculations of the equations. Simulations are carried out for refraction and reflection of weak shock waves by an inclined interface. Computed results are compared with wave patterns obtained from Huygens' principle as well as reflection coefficients of sound waves. Good qualitative agreement is obtained and it is concluded that the present model equations are convenient to predict phenomena induced by shock propagation in nonuniform liquid.
