The aerodynamics of electric arcs in axial flow
thesis
posted on 2013-11-21, 12:43 authored by David R. TophamThis thesis investigates the behaviour of a d.c. electric
arc under the influence of a number of different axial gas flow
conditions. The work is directed towards obtaining a greater
understanding of the electric arcs produced within gas blast
circuit breakers. In order to eliminate as many variables as
possible, detailed experiments have been carried out in constant
pressure, subsonic nitrogen flow provided by a low Mach number
shock tube. This facility enables the flow velocity and pressure
to be varied independently, thus allowing their effect on arc
behaviour to be studied separately. A simplified theoretical
model of the arc in this flow field has been developed which gives
excellent agreement with the shock tube experiments. The solution
of the theoretical model is obtained in non-dimensional terms as a
universal characteristic for the constant pressure axial flow arc…
