Can a field help water reach a surface?
An electric field can alter the motion of a charged droplet. Making that useful requires the droplet to reach a collector, drain and stay out of the airflow. The powered-versus-passive comparison keeps the physical collector in place and asks what energizing the system changes. Collection and visibility remain separate endpoints.
Questions worth measuring
- What is gained over the identical passive collector?
- How does collection vary with droplet size and flow?
- What is the complete electrical and pressure-drop cost?
The records below are a starting point for those questions. Read the original methods and results before applying a finding outside the tested setting.
