Investigations to Decrease Losses in Magetohydrodynamic (MHD) Generators
Abstract
The research program described in the report has included work on boundary layer studies, current distribution and current leakage in MHD generators, and boundary layer diagnostics. A computer program which has been used successfully to calculate conventional turbulent boundary layers has been modified by adding the MHD terms in the momentum and energy equations. Current patterns in conducting wall generators were measured and showed good agreement with theoretical predictions for the anode. The surface-sheath voltage drop was responsible for less good agreement at the cathode. A new method which uses Faraday splitting of laser modes is suggested for the measurement of electron concentration in the boundary layer. A laser doppler velocimeter and its applications to boundary layer velocity measurements in the Stanford generator is described.
