Steady Laminar Compressible Magneto-Fluid-Dynamic Gas Flows in Channels.


Harstad, Kenneth Gunder (1967) Steady Laminar Compressible Magneto-Fluid-Dynamic Gas Flows in Channels. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/5T8X-8S80.


Numerical computations are carried out for the core flow of subsonic MFD generator channels with a large length-to-height ratio and fine electrode segmentation. The working fluid is taken as potassium seeded argon. Variable transport properties and radiation effects are considered. It is shown that transverse variations in fluid properties are very important in Faraday generators; a one-dimensional analysis of the flow is not adequate. Axial currents in nonequilibrium flows can be kept low if the right value of the Hall parameter can be obtained; this also depends critically on the Mach number and load parameter. Mach numbers much less than one and high load parameters are to be avoided. Attainment of very large Hall parameters and fields cannot be expected.
