AN EXPERIMENTAL STUDY OF THE TWO-PHASE FLOW ADJACENT TO A WIRE IN NUCLEATE BOILING UNDER AN ELECTRIC FIELD

摘要

An experimental study of the two-phase flow near a heated wire in nucleate pool boiling is presented. A nonuniform electric field of cylindrical geometry was imposed to the heater. The two-phase flow parameters were measured using specifically developed local phase-detection optical probes. The study includes experiments varying the vertical distance from the heater (z) and measures of the void fraction and the impact rate in a plane perpendicular to the heater (y-z).
