Abstract

Friction factor and wall heat-transfer data for axially symmetric flow in a wall-stabilized arc analysis are given. Heat transfer results revealed three significant modes: laminar flow with an unstable arc, laminar flow with a wall-stabilized arc, and turbulent flow with a wall-stabilized arc. It was shown that the critical Reynolds number increases, in comparison with the case of the flow without Joule heating. A friction factor from Reynolds-number dependence peculiarities was not discovered for laminar to turbulent flow transition
