Enhancing Martian Dust Filtration Through Advanced Corona Discharge-Based Electrostatic Precipitators for Sustainable Human Exploration

Abstract

This study explores the application of corona discharge-based electrostatic precipitators (ESPs) for efficient Martian dust filtration, essential for long-term human exploration on Mars. Utilizing innovative electrode configurations, including zigzag plate electrodes and variable spacings, the research predicts significant improvements in dust capture efficiency, driven by optimized electrohydrodynamic (EHD) forces. These forces prove highly effective at lower gas flow speeds, though their impact diminishes at higher speeds, leading to reduced efficiency. The results underscore the potential integration of ESP systems into Martian habitats to manage atmospheric quality and safeguard critical systems, marking a crucial advancement in Martian in situ resource utilization (ISRU).
