Narrow Results

The design project of color night vision method of dual-spectrum low light level (LLL) in single-channel is presented, and the simulating result of the method is given too. The method is based on filter film of separating spectrum that separates LLL CCD image into two parts, which are long wave stripe image and short wave stripe image. Compensating between frames are done to long wave stripe image and short wave stripe image respectively; long wave (LW) image and short wave (SW) image after compensating are fused and hue space mapped; color display image is obtained to increase identifying probability. The color night vision method of dual-spectrum LLL in single-channel resolves problems of matching difficult, bad real-time and high cost in the color night vision system of dual-channel.

The water droplets motion and trapping in single-channel of corrugated plate gas-liquid separator is studied by using the commercial software, Fluent 14.5. The performance of two types of streamlined plates is evaluated by adjusting gas velocity and transverse pitch. The results show that high gas velocity and narrow transverse pitch is helpful to improve the efficiency but also with relative high pressure drop. The streamlined plates with hook have higher separation efficiency to the small droplets than the plates without hook. Final results of numerical analysis can guide the practical applications in industrial processes.
