Static and dynamic properties of arcs near plane surfaces

The static properties of an arc near a plane surface have been analyzed by extending Maecker's method to bi-cylindrical coordinates. A direct numerical solution was also carried out. The general method of Phillips was then used to predict the transient properties. Experimental data was taken on the static and dynamic properties of arcs burning near dry and wet surfaces. Agreement with theory was much better for dry surfaces, suggesting that humidity in the arc greatly affects the static and dynamic properties.
