摘要: Nucleate boiling heat transfer for refrigerants, R113, and R113+ wt4% ethanol mixture, an azeotropic mixture under electric field was investigated experimentally in a single-tube shell/ tube exchanger. A special electrode configuration which provides more uniform that produces higher voltage limit against the dielectric breakdown used this study. Experimental study has revealed electrical charge relaxation time is important parameter enhancement field. Up to 1210% of obtained R113+wt4% 0.0053 sec whereas only 280% R113 0.97 sec. With artificially machined surface, coefficient obtained.
