ALEX results: A comparison of measurements from a round and a rectangular duct with 3-D code predictions

Abstract

Recent results of liquid-metal magnetohydrodynamic (MHD) measurements from a rectangular duct and earlier measurements from a round duct are reported. A fully three-dimensional numerical analysis of each test section in the fringing region of an applied magnetic field is briefly described. The results of the experiments and the 3-D code predictions are compared and discussed. Excellent agreement is obtained in both test section geometries for interaction parameters ranging from 500 less than or equal to N less than or equal to 1.25 x 10/sup 5/. 9 refs., 7 figs., 1 tab.
