Abstract : The operation of a peristaltic magneto-fluid dynamic induction compressor has been studied theoretically and the specialization of such a compressor to underwater propulsion has been suggested. The principles of operation involves using a sinusoidal current sheet traveling on a coil to drive a highly conductive fluid in an annulus within the coil, mechanically coupling the resultant forces to a less conductive fluid in another annulus within the first, and deriving thrust from the pressure rise thus generated in the less conductive fluid. The study assumes efficient mechanical coupling between the fluids by a flexible diaphragm, low joulean losses in the conducting fluid, and negligible flow separation losses between the accelerated fluid and medium. The study concludes that induction compressors could propel submarines and torpedoes with very high efficiency and could be developed for a variety of other applications. (Author)
