Abstract
The relationships p = p (Q) and U = U (Q) (at different values of I and B) for two channels of a conduction-type magnetohydrodynamic pump were analyzed using equations containing both dimensional and dimensionless coefficients. The variables were quantities connected with the determining criteria of magnetohydrodynamics. It is shown also that, with a degree of accuracy sufficient for practical purposes, the above coefficients can be determined analytically, using the known distribution of the relative induction along the longitudinal axis of the channel B_∗(x). The results of the work can be used for analyzing experimental data on conduction-type magnetohydrodynamic pumps.
