  • Abstract The issues of effluent discharged into the marine environment and jet diffusion are interesting. Ex. The plant along the coast, the emission tube of effluent processing plant, the brine water discharged into the sea after desalination and the thermal effluent caused by cooling system of fired power and nuclear plant. The effluent either has higher or lower density compared to seawater, and it actually happened in our daily life. Thus, the jet diffusion analysis and research method of discharged effluent in the environment are also worth seeking.
    This experiment applied the image analysis to analyzing the track of jet diffusion. Further adjusted the image analysis to meet the distribution of the section concentration of jet diffusion. This experiment was filmed with fixed equipment and horizontal jet diffusion tube, and then changed the concentration and speed of the jet diffusion. Firstly analyzed the image data with image analysis by converting the filmed color into relative concentration to understand the concentration spread of jet diffusion. Secondly converted the taken down net point into actual coordinate to find the section concentration of centerline and the line vertical to the centerline. Finally understood if there was reappearance and compared the centerline analysis with theory result by repeat experiments. This experiment utilized the image analysis to understand the jet diffusion concentration spread of both Buoyant jet and negatively buoyant jets and the result showed that the farther the jet diffusion distance is, the quicker concentration spreads and the higher dilution rate will be.
