Abstract : A study of arc column rotation in a 4 ring ac arc heater without an external magnetic field is presented. Arc column speed is found to depend upon arc current, arc heater pressure, amount and direction of air injection and electrode geometry. The methods used for the experiments and the evaluation of the filmed data are described and justified. Arc heater efficiency and stability has been improved as a result of this work. (Author)
