内容記述 | In this report, presented are the experimental results of the diffusion process in a circular jet of a dye solution issuing into a quiescent water. Also a semi-empirical theory for the radial profile of the concentration fluctuation intensity is presented. Measurements of the concentration field for a dye solution were performed by a light absorption method because of the simplicity of its measuring principle and movability of the probe. Experimental results showed that the radial profiles of the mean axial velocity and mean concentration had well-known Gaussian distributions respectively. A self-preserving form for the profiles of the concentration fluctuation intensity was observed in the downstream region, x/d_N ≥100. Using these experimental results and assumtions of the gradient type diffusion process, an analysis and calculations are presented on the self-preserving profile of the concentration fluctuation intensity. | |||||
