Pool boiling in the presence of an electric field and in a variable gravity field: results of experiments in parabolic flight.

Author(s) : DI MARCO P., GRASSI W.

Summary

The electric field has an influence on boiling heat transfer, and can act as a replacement of buoyancy in the absence of gravity. An experimental facility was set up to investigate pool boiling on a platinum heated wire in the presence of an electric field and in microgravity. The working fluid was R113. On-earth experiment revealed that the critical heat flux undergoes a three-fold increase or more by applying a high voltage cylindrical electrostatic field around the wire. Nucleate boiling performance is on the contrary slightly affected in the present configuration. The facility was then operated in parabolic flight at an acceleration level of 0.03 gravity acceleration. Results are given.
