WebbThe traveling wave speed, plateau (rightmost) density and velocity are obtained from the Rankine-Hugoniot viscous shock conditions for a piston. The fitting parameters are the nondimensional viscosity ν = 25 and the traveling wave center z 0 = −25 μm, obtained by minimizing the sum of the absolute differences between the filtered and traveling wave … WebbA spherical or cylindrical cavity containing quiescent gas begins to contract at high constant radial speed, driving an axisymmetric shock wave inward to collapse at the centre. We analyse the flow field by expanding the solution in powers of time, and calculate 40 terms by delegating the arithmetic to a computer.
Piston driven converging shock waves in a stiffened gas
WebbA high-pressure field is generated in a circular tube by introducing an unsteady jet from its open end. The head of this jet acts as a piston, driving compression waves ahead of it. The peak value of the induced overpressure is evaluated as a solution of a Riemann problem, wherein the jet head is equivalent to a piston head. The jet head of the driver gas, with a … Webbcylindrical tube, which is fitted with a piston atone end (x = 0) and closed at the other end. Figure A shows the time-dependent flow that results when the piston Fig A. Compression in a Shock Tube is suddenly pushed into the cylinder and how a shock front forms as sonic disturbances generated by the piston converge.
