Abstract : The flow of a viscous, heat-conducting gas produced by an accelerating piston is analyzed numerically. The formation of a shock in a viscous flow is studied. A discussion of accuracy and practicality of a numerical analysis of the problem is given. It is concluded that, although very accurate results may be obtained, in principle, regardless of the Reynolds number of the flow, the assumption of a shock as a sharp discontinuity is the only practical way to handle flows whose Reynolds number per unit length is higher than 100.
