The Effect of Frequency and Duty Cycle on Heat Transfer and Pressure Drop for Convective Condensation under Pulsed Electric Field

The effect of pulsed electric fields on heat transfer and pressure drop in horizontal in-tube convective condensation has been investigated. In particular, the effect of the frequency and duty cycle of an applied pulse wave between 0 and 8 kV was studied for frequencies in the range 0.5 Hz to 1.5 kHz and for 25 %, 50 % and 75 % duty cycles. The electric field was applied through a central electrode along the centerline of the tube. The …
