At the same time, a special device braked the piston and the gas flow was cut off from the ampoule.
The waves propagating from an oscillating plane piston into a vibrationally relaxing gas are calculated by an exact numerical method ignoring viscosity and heat conduction.
The present treatment removes the restriction of isentropic flows, extending the applicability of piston theory to flows with strong shocks.
The contact boundary of gases was accelerated by means of a compression wave, which was generated by an accelerating piston.
The rubber shock absorber located at the bottom of the outlet section is designed to cancel the residual speed of the piston.
The stroke of the actuators has been limited to 80% of the total length of the piston.
With sufficient separation, when the shock front is in radial motion, the magnetic piston is still moving axially.
However, the pressure acting on the front face depends on the motion of the piston and on the compression waves generated by it.
