Abstract:
In order to explore the thawing mechanism of high voltage electrostatic field, and improve the thawing technique as well as the thawing efficiency of the high voltage electrostatic field, contrast experiments of thawing rate on ice using a needle electrode, a wire electrode and a plate electrode with different voltages had been evaluated in this study, respectively. At the same time,?the contrast experiments of thawing rate on ice using a needle electrode with and without glass enclosures and the effects of the wire’s electrode spacing and the distance between the two neighboring wires on thawing rate were investigated. The results indicated high voltage electrostatic field formed by a plate electrode that couldn’t??improve the thawing rate obviously, while a needle electrode and a wire electrode could improve the thawing rate significantly, the thawing rate of ice with plus glass enclosures was much lower than that without glass enclosures, and the electrode spacing and the distance between the two neighboring wires could effect the thawing rate, and it is thought that corona wind produced by the electrode, which resembles a round jet, impinges and thaws the ice.
