| Abstract: | The diffusion coefficient is an important parameter of seawater pollutantdiffusion. The purpose of this experiment on tracer diffusion is to understand thedilution and diffusion capability of water current movement, and calculate horizontallongitudinal and transversal diffusion coefficient for mathematical simulation of waterquality according to the moving track of tracer and the distribution of itsconeentration. The diffusion coefficient of seawater in Daya Bay is obtained by fieldexperiment of tracer diffusion. By instantenous discharge of the tracer anddiscontinuous sampling, the horizontal diffusion coefficient was obtained, while by continuous tracer discharge and standard synchronical sampling, the transversal diffusionwas derived. |
