Summary: | This paper describes an experimental study and a quasi-one-dimensional calculation of acceleration of dispersed particles by gas detonation products in an expanding channel. The calculations show the possibility of a significant increase in the velocity of powder particles due to the conical expansion of a detonation channel. For particles with sizes of 30–40
m at cone angles of 2–4°, the maximum velocity increase reaches 35–60%. A method is developed for fixing the radiation of a packet of dispersed particles accelerated in a detonation channel by a photosensor, which makes it possible to measure the particle velocity with an accuracy of
5%. The calculation results are in good agreement with the experimental data. |
