The effects of corona wind on the heat transfer rate from a heated horizontal cylinder are described. Corona discharge and a corona wind are developed when a high voltage is applied to an electrode (emitter) near a grounded surface. In this study the corona wind is directed toward the lower region of the grounded cylinder by placing either a positively charged single-wire emitter or multipoint emitter parallel to and directly below the heated cylinder. Heat transfer rates from the heated cylinder under free convection conditions with and without a corona wind are obtained by measuring the power input to the cylinder. Free convection rates are also obtained from interferometer photographs. Free convection heat transfer rates are increased several times by the corona wind.
