The spatial pattern of AWLRU zoning was consistent with the condition of water resources and the characteristics of land use.
The investigation was carried out for a wide load range of 200 MW-700 MW in the condition of water head 57 m-90 m.
The flow condition of water supply pipelines are affected by terrain, buildings and other external factors, easy to produce the complex phenomenon of hydraulic transient.
Under the condition of dry friction, wear losses increased with the increasing load and the main wear mechanism is both severe adhesive and abrasive wear; under the condition of water existence, the applied loads would not affect the wear losses, and the wear mechanism is abrasive wear.
The general features of water transport in PEMFCs are discussed to show various water transport regimes of practical interest, such as anode water loss, cathode flooding, and the equilibrium condition of water at the channel outlets, particularly for limiting situations where anode and cathode water profiles acquire an equilibrium state.
The results show that, under the condition of water vapor content at 0.25%, oxygen content at 20.8%, initial concentration of TCE at 303.32 ppm, input light amount at 3.07 × 1017 s−1 and residence time at 1.6 s, the apparent photon quantum efficiency is 26.31%, the turnover frequency is 12.44 μmol/(g TiO2 min) and the removal efficiency is 86.66%.
