| Abstract: | Detonation propagation velocity in a rough tube taking account of heat loss and friction was investigated analytically and numerically. The flow in the reaction zone is assumed to be one-dimensional and quasi-steady. An analytical expression describing the detonation structure and the combine effects of heat and momentum loss on detonation velocity was obtained. Numerical simulation of the detonation wave structure was also made. Detonation limit and multiple detonation regimes were examined. The propagation mechanism of the low velocity detonation was explained. The result shows that the structure of low velocity detonation has been changed because of the increasing effect of friction. |
