The experimental investigation of heat transfer enhancement of dielectric fluid in electrostatic field

The insulating fluid with low boiling point R11 was selected as working fluid and an experimental model was designed and made. The experiment on condensation heat transfer inside this model was conducted under electrostatic field. The experiment results showed that the electrostatic field can enhance the condensation heat transfer of the dielectric fluid inside the model greatly, and the heat transfer coefficient was mainly affected by applied electric field, heat flux and the relative position of the electrode. This electric field enhanced condensation technology show much reference value for refrigeration and heat transfer engineering.
