On the Effects of Viscosity on the Shock Waves for a Hydrodynamical Case—Part I : Basic Mechanism

الملخص EN

The interaction of shock waves with viscosity is one of the central problems in the supersonic regime of compressible fluid flow.

In this work, numerical solutions of unmagnetised fluid equations, with the viscous stress tensor, are investigated for a one-dimensional shock wave.

In the algorithm developed the viscous stress terms are expressed in terms of the relevant Reynolds number.

The algorithm concentrated on the compression rate, the entropy change, pressures, and Mach number ratios across the shock wave.

The behaviour of solutions is obtained for the Reynolds and Mach numbers defining the medium and shock wave in the supersonic limits.
