Boiling heat transfer of liquid nitrogen in the presence of electric fields

Boiling heat transfer of liquid nitrogen in the presence of electric fields
Boiling heat transfer of liquid nitrogen in the presence of electric fields
An experimental study has been undertaken to determine the influence of a d.c. uniform electrical field on boiling heat transfer of liquid nitrogen (LN2). A copper block electrode with temperature measurement and vacuum heat insulation was designed and manufactured. The effects of electric fields on boiling hysteresis, nucleate boiling and critical heat flux have been analyzed and discussed. The results obtained may help the design of the LN2 related components for HTS device cooling and also provide an initial perspective on the possible improvements for cryogenic cooling of HTS equipment.

Abstract

An experimental study has been undertaken to determine the influence of a d.c. uniform electrical field on boiling heat transfer of liquid nitrogen (LN2). A copper block electrode with temperature measurement and vacuum heat insulation was designed and manufactured. The effects of electric fields on boiling hysteresis, nucleate boiling and critical heat flux have been analyzed and discussed. The results obtained may help the design of the LN2 related components for HTS device cooling and also provide an initial perspective on the possible improvements for cryogenic cooling of HTS equipment.
