Abstract:

A practical way of transferring large amounts of energy to a gas on a steady-state basis is by passing it through an electric discharge. The basic problem is to produce a uniform, steady flow of high temperature gas of any desired composition. Thus, the problem of arc heater design is to provide means for maintaining a high energy density in a volume no larger than required to establish a uniform flow and to sustain this process indefinitely with a minimum or no contaminate into the exit heated gas. The principal limiting factors of higher performance heaters are heat transfer and its affect on component life or contamination, component and system structure strength, and energy transfer efficiency. To obtain design criteria analytical models are developed and utilized to predict energy transfer, flow, temperature, pressure, current and voltage gradient relationships experimental diagnostics are applied to check, evaluate, improve and to provide empirical data for the analytical models. This process, the models that have been developed, the experimental diagnostics and the initial results are presented. Author
