Development and application of a simplified radiative transport equation in water curtain systems

Finally, the important engineering parameters such as the mass flow rate, the droplet mean diameter, the number density, the optical depth, and the reduced intensity are systematically investigated. It can be predicted that optical depth (τ > 0.89), number density (N > O(4 × 106 m−3)), droplet mean radius (rm < 180 μm) and flow rate (Qflow > 1.2 kg/s) are determined to reduce the radiation intensity less than 50% for the selected water curtain nozzle in this study.
