KIVA-I Extended Duration MHD Generator Development.
Abstract
An extended duration magnetohydrodynamic (MHD) generator system was developed. This system consists of the MHD combustor, nozzle, generator channel, diffuser, high speed data acquisition system and high voltage converter. Two steady-state generator channels were designed: a pegwall channel and a diagonal conducting wall channel. The pegwall channel was only constructed in a shortened version of the generator channel and was not tested for power output. The diagonal conducting wall generator was tested for several minutes of power generation both in steady-state and pulse mode. The channel appeared unaffected by the duration or type of testing conducted. A high speed data acquisition system was incorporated into the KIVA-I test facility. This system features a PDP-8/M system controller, two DEC magnetic tape units and a CRT display. This system samples data continuously at a 16.7 KHz rate and permits rapid recovery and evaluation of test data.
