Transmission of bubble detonation through a layer of an inert liquid

The possibility of detonation transmission through a water plug from one column of a chemically active bubbly medium to another is experimentally verified. The critical length of the liquid plug is determined. The experiments are performed in a shock tube with bubbles of a stoichiometric acetylene–oxygen mixture in water. The character of peak-pressure decay after detonation-wave departure from the bubbly medium to the liquid is established. It is shown that the pressure profile retains similarity as the compression wave propagates over a discrete gas–iquid medium.
