✦ Synopsis

The apphcation of an alternatmg electnc field to cause movement of partxles charged naturally by contact elect&cation m a fludlzed bed, has been demonstrated as a techmque for mcreasmg the heat transfer coeficlent at an unmersed heater surface The optimum heat transfer coeffictent was found for frequencies m the remon of 100 Hz, and mcreases m the heat transfer coefficient of up to 140% were obtamed A serm-quantitative explanation of the observed behavior IS even, and the apphcation of the techmque to paper or textie drymg IS suggested
