Modelling for EHD enhancement of boiling heat transfer

A mathematical model of EHD enhancement of boiling heat transfer is proposed on the bases of boiling theory, EHD enhancement heat transfer analysis, and the experimental data of R11 obtained when applying high voltage D C on a vertical tube. With the equation of the model, EHD enhancement coefficient of boiling heat transfer may be calculated. The maximum difference between the formula result and the test data is less than ±30%.
