Assessment of Particle Dynamics in Electric Air Filters: The Role of Ionic Wind in Air Quality Improvement
摘要
This study investigates the dynamics of quartz sand particles in an electric air filter using ionic wind, focusing on the interplay between aerodynamic forces and electrostatic effects. Utilizing a Python-based simulation, we analyzed particle behavior under varying air flow rates and particle sizes. The results indicate that smaller particles exhibit more dynamic changes in position, velocity, and acceleration due to their lower mass and higher sensitivity to drag forces. Higher air flow rates above 400 m3/h result in more pronounced positional changes and higher initial velocities. The ionic wind effect significantly influences particle trajectories, particularly for smaller particles of 0,3 µm, 0,5 µm, by pushing them towards the pipe walls. This study underscores the importance of considering both aerodynamic and electrostatic effects in air filtration system design, providing a foundation for future research aimed at improving air quality in urban and industrial environments. The findings have significant implications for pollution control and public health protection.
