| 總結: | This project describes an investigation of a flame imaging system using Laser-
Based Tomography. The main purpose is to obtain the concentration profile of the flame
to be incorporated in Laser-based transmission tomography measurement system for
combustion on-line monitoring. The system can be applied to produce cross sectional
images of flame such as that in a combustion chamber. Such a system can be employed to
compare the effectiveness of different fuel additives and to monitor the onset of knock
with various fuel formulations or cylinder head geometries. The ability to monitor the
size, position and velocity of flame fronts in any combustion behavior and emissions. The
concentration of this project is to determine the position and velocity of flame fronts in
the pipeline by using photodiode (BPX 65) as sensor and Helium Neon Laser as laser
sources. Laser will emit to pipe and the emitted light will strike to the photodiode through
optical fiber as carry the laser light sources. To completely expand the laser light, the
emitted light will collimated by a lens as is passes through the pipe walls. The system
employs two orthogonal projections with one laser source. The laser source will supply 12
light beams, so the cross section of the pipe being interrogated by a total of 12 beams. In
this case, we assume that the flame is placed in specific places in the measurement cross
section and voltage output will calculated by the individual sensor is modeled. Besides the
hardware, this project will include an interface user friendly, Visual C++ to visualize the
concentration profile of the flame |
