On the properties of curvilinear shock waves 'smearing' in calculations by the particle-in-cell method
Abstract
It is shown by the 2-dimensional numerical computations of the cylindrical shock wave propagation using the particle-in-cell method that the width of a 'smeared' shock wave zone reaches its minimum at some non-zero inclination angle of the velocity vector with respect to the x-axis in the 'smeared' shock wave. Results of theoretical analysis of the characteristics of the smeared shock wave zone width dependence upon the flow orientation with respect to the rectangular computing mesh lines carried out by the use of the first differential approximation method agree well with calculation results.
