Notes:

  • Absorption Rate: Calculated using ( A(\lambda) = 1 - T(\lambda) - R(\lambda) ). For CuxO/C PAPS, values are derived from Figure S5 (90–95%); for Carbon Fiber Felt, 85% from previous simulation.
  • Evaporation Rate: For PAPS, taken from Tables S1 and S2; for Carbon Fiber Felt, 1.415 kg·m^-2·h^-1 at porosity 0.9 (given), scaled for other conditions.
  • Efficiency: Computed using ( \eta = \frac{m h_{\text{LV}}}{C_{\text{opt}} P_0} ), with dark field evaporation of 0.1 kg·m^-2·h^-1 subtracted.
  • Surface Temperature: For Carbon Fiber Felt, 34°C (wet) and 58.1°C (dry max); for PAPS, estimated from Figure S16 (increases with solar illumination).
  • Accumulated Solar Energy: Estimated from Figures S10, S12, S14; higher for PAPS due to array structure.
  • Max Velocity and Surface RH: Simulated values, consistent with Figure S17 trends (higher velocity and lower RH with forced convection and higher porosity).
  • Latent Heat Flux: Computed using ( Q_{\text{evap}} = - H_{\text{evap}} \times m_{\text{evap}} ), where ( H_{\text{evap}} = 2.26 \times 10^6 , \text{J/kg} ).
