@article{Edwards1979TheDO, title={The diffraction of a planar detonation wave at an abrupt area change}, author={D. H. Edwards and Geraint O. Thomas and Michael Arthur Nettleton}, journal={Journal of Fluid Mechanics}, year={1979}, volume={95}, pages={79 - 96} }

Previous experimental work on the diffraction of a detonation wave at a large and abrupt area change in a tube, has shown that every system is characterized by a critical tube diameter at which quenching of the detonation occurs. Zeldovich, Kogarko & Simonov (1956) established that the critical tube diameter, for the oxy-acetylene system with varying dilution of nitrogen, lies between 500 and 700 times the one-dimensional induction zone length. Later, Mitrovanov & Soloukhin (1964) discovered…
