A numerical method has been developed for solving the equations of compressible fluids by using the particle method. In our method, the particles move at the acceleration or velocity which is defined for each equation. In addition to the density, the acceleration and the velocity are expressed by the summation of the contribution from each particle, which has a pre-determined amount of a physical attribute. To show the validity of our method, the wave equation, Burgers equation and the equation for a compressible fluid, both with and without a diffusion term, all one-dimensional, are considered. The generation of the shock and expansion waves, the formation of the steady shock wave, and the interactions of the linear waves and of the nonlinear shock waves, are successfully simulated by our method.
