dc.description.abstractThis study investigates the enhancement of electrohydrodynamic (EHD) flow velocity in a multi needle-tocylinder configuration using an electromagnetically assisted system under atmospheric conditions. An experimental setup was developed to measure airflow velocity, incorporating a corona discharge emitter, solenoid, and precise instrumentation. The impact of emitter voltage, solenoid voltage (magnetic field strength), and needle-tocylinder distance on airflow velocity was evaluated using factorial analysis. The results highlight the role of the solenoid-generated magnetic field in enhancing EHD flow velocity via Lorentz forces. The maximum air velocity of 2.10 m/s was achieved with a maximum emitter voltage of 20.63 kV, emitter distance of 18 mm, and solenoid voltage of 30 V. Applying Lorentz force increased air speed by 4.9-56.7 % for different emitter voltages and distances compared to zero solenoid voltage. With a solenoid voltage of 15 V, the increase ranged from 4.9 % to 35.5 %, and with 30 V, it ranged from 8 % to 56.7 %. The average velocity increase was 18.63 % for 15 V and 39.94 % for 30 V. At a fixed emitter voltage and distance, increasing the solenoid voltage enhanced velocity, demonstrating the influence of Lorentz forces on ion acceleration and momentum transfer to air molecules. Pareto analysis confirmed that both solenoid and emitter voltages significantly contribute to flow enhancement. These results highlight the importance of Lorentz forces in enhancing EHD flow and suggest that optimizing solenoid voltage could improve the performance of EHD-based technologies in applications like heat exchangers, cooling systems, and microfluidic devices.
