Abstract
Results of experimental and numerical study of maximum pressures and impulses developed in closed vessel as a function of DDT location are presented. Experiments were carried out in the detonation tube with stoichiometric hydrogen-oxygen mixture diluted with nitrogen. The effect of two variables was investigated: distance between tube closed end and DDT origin, and the ratio of burned and unburned mixture volume prior to the DDT moment. It was found that impulse value is proportional to the total length of tube and does not depend significantly on DDT location. Results of numerical simulation are in good agreement with experimental data.
