MHD channel development
Abstract
The modelling of the diagonal channel with resistive links was completed. A second series of laser doppler velocimeter (LDV) experiments was conducted on the Avco Mk VI channel using diagnostics provided by Mississippi State University. A long-duration test of the Mk VII channel with the objective of side wall development is in progress. Electrode drops in the Mk VI Reference Channel No. 4 operating without slag were measured, over a range of gas conductivities and magnetic field strengths. A set of master/slave current consolidation and control circuitry was tested for 40 hours on the Mk VII channel. The testing is continuing in parallel with the long-duration sidewall testing in progress under Task 2. The Mk VI and Mk VII test facilities were operated for a total of 73 hours: power was generated for 30 hours. The supersonic section of the Reference 4 diffuser was reworked to allow simultaneous use of the stagnation pressure probe and the LDV. Shim plates were added to the Mk VI magnet.
