Electrohydrodynamic (EHD) flow and convective boiling augmentation in single-component horizontal annular channels

In order to explore the mechanics of EHD induced flow and heat transfer augmentation, an experimental study of the tube-side boiling heat transfer of refrigerant HFC-134a has been conducted in a single-pass, counter-flow heat exchanger. The electrode position was arranged concentric to the tube. Experiments are conducted for inlet qualities of 0% to 60%, mass fluxes from 100 kg/m²s to 500 kg/m²s, heat fluxes of 10 kW/m² and 20 kW/m², and …
