THE PERFORMANCE OF A FAMILY OF DIAGONAL CONDUCTING WALL MHD OPEN CYCLE GENERATORS,
Abstract
Experimental and theoretical studies were made of the performance of a 45 deg diagonal conducting wall generator and a Hall generator of the same physical dimensions. The wall temperature effect is investigated and an arc model is proposed. Aluminum was successfully burned in the combustor. It was found that the coating from burning of aluminum improves the channel performance due to the heating up of the walls. It was found that the fluctuations present in the Hall channel have much higher frequencies than those in the 45 deg DCW channel. The fluctuations grow along the channel in the Hall mode. The presence of the aluminum attenuates the fluctuations. The effect of the low conductivity nonuniformaties in the plasma and the coating of the wall has a very profound effect on the performance of the Hall generator. (Author)
