FLOW OF HIGH-DENSITY IRON PLASMA IN GAS-FILLED PIPES AND MUFFLERS.
Abstract
An experimental program was conducted to investigate the flow of high-density, high-velocity iron plasma in gas-filled mufflers and pipes. The experiments were directed toward the investigation of: (1) the flow of plasma through gas-filled mufflers, (2) the flow of plasma in gas-filled pipes without mufflers, and (3) the rapid filling of an evacuated tank with detonation products by detonating high explosive within the tank. The experimental results indicate that filling a muffler with gas does not increase its effectiveness over that of an evacuated muffler and may even decrease its effectiveness. The results show, however, that filling a straight pipe with gas increases the rate of momentum transfer and loss of kinetic energy to the pipe. The results also show that a concentrated slug of plasma is produced on partial stagnation of the plasma by the gas and that the slug loses mass during the early part of its travel down the pipe and gains mass further down the pipe after it has cooled. Possible mechanisms for the loss and gain in mass as well as the transfer of momentum to the pipe are discussed. (Author)
