Schematic of the ELDC configuration to protect optical/photovoltaic surfaces at the worst case scenario.
The ELDC geometry and particle placement in sections 1 and 2 (100 lunar dust particles at the middle initially forming a line inside the particle factory; L = W = 10 cm and D = 5 cm).
Sensitivity analysis on electrical screening distance around the particles (one hundred 20-μm-sized particles at uniform electrostatic field; L = W = 10 cm, D = 5 cm, and ΔV = 100 V).
Collection efficiency as a function of provided voltage via 3 different models: Lagrangian-based approach with a uniform e-field, Lagrangian-based approach with a non-uniform e-field, and Eulerian-based approach. In all 3 models: dp = 20 μm, φs = 100 V, L = W = 10 cm, and D = 5 cm).
Effect of particle number concentration on collection efficiency ofthe ELDC (dp = 20 μm, φs = 100 V, ΔV = 100 V, L = W = 10 cm, and D = 5 cm).
The ELDC capacitance at different number of subsections (L = W = 10 cm and D = 5 cm at ΔV = 100 V).
Distribution of surface charge on ELDC plates at 4 different provided voltages (pC).
DEM results for two different sizes of the ELDC and comparison with Eulerian-based model.
