Book Description
An experimental study was performed of the operating characteristics of a large linear, supersonic MHD generator. A shock tunnel was used to heat the test gases, which was primarily a 99 percent neon + 1 percent xenon mixture, to stagnation pressures of 1 to 5 atmospheres, temperatures of about 3500 degrees K, and electron densities on the order of 10 to the power of 10/cc. The test time of 5 milliseconds, which was about 10 times the traversal time of the gas through the generator, was sufficient to produce quasi-steady state conditions in the channel. (Author).

The test time of 5 milliseconds, which was about 10 times the traversal time of the gas through the generator, was sufficient to produce quasi-steady state conditions in the channel. It was concluded that electrode conduction losses and shock wave formations were the two major factors limiting the efficiency of this generator. (Author).

Book Description
The report presents a summary of the progress during the past year on a continuing investigation aimed at determining the operating characteristics of the linear, non-equilibrium MHD generator. The main effort of the past year was concentrated on reducing the electrode losses in the generator by using heated electrodes which protruded into the gas stream. Using an MHD channel, which was specially constructed for this purpose, large scale electrical power was obtained for the first time in cesium seeded, noble gases at gas stagnation temperatures as low as 2000K. Various electrode structures, both hot and cold, were investigated; but the electrode design was not as important as the cesium concentration in determining the electrode drops. During the past year, construction of a larger MHD channel and of a considerably more powerful MHD magnet and power supply were nearly completed. (Author).
