【 摘 要 】

A 2D-laser doppler velocimeter was used tomeasure velocities of reacting boron (B) particles during thecombustion of a metallised solid fuel slab inside a 20-combustionchamber. The solid fuel hydroxyl-terminated polybutadiene (HTPB) wasenriched with B particles to increase its specific heat. To obtaininformation on the combustion process and on the movement of Bparticles, their velocities were measured. The experiments wereperformed at ambient pressure. The behaviour of the B particlesconcerning the exit velocities from the fuel slab has been discussed onthe basis of the experimental results.
