Analytical model of free-piston motion including diaphragm opening for free-piston shock tunnels

What is it about?

We propose an analytical model to predict the piston motion of free-piston shock tunnel including diaphragm opening time.

Why is it important?

We can estimate the effect of the diaphragm opening time of the performance of free-piston shock tunnels. The effect becomes significantly important for relatively small-to-medium size ones.
