摘要: This work deals with the assessment by numerical investigations of electrohydrodynamic enhancement heat transfer in a channel. In order to get better understanding phenomena, we developed an original approach. The model handles couplings between non-isothermal turbulent flow and corona discharges from multiple wires. typical configuration consists channel where air enters at given velocity. channel, ionic wind is produced coronating this study, used analyse effect some process parameters (inter-electrode distance, wire radius, applied voltage) on convective enhancement. We firstly confirm that operates well permits selection best specific configuration. reveals similar flows could be obtained different combinations inter-electrode distance voltage. second stage, adjacent wires discussed. Synergetic effects are for close wires; they locally lead tenfold increase
