不同构型电晕放电离子风强化传热的数值模拟研究

In order to investigate the heat transfer performance of ionic wind under different configurations, numerical simulation of three ionic wind devices with different structures was performed, and effects of voltage, electrode height and fin width on average wind speed, heat transfer coefficient and power were explored. The results show that voltage increase can improve heat transfer enhancement of ionic wind, but power consumption increases with the wire-plate type the highest power consumption. Smaller electrode height resulted in better heat transfer enhancement. Moreover, the direct grounding type electrode is found more suitable for short heat sink width and low heat dissipation demand due to its low power consumption. The results provide an important reference for the selection of ionic wind structures under different conditions.
