Abstract
This research aimed to clarify the disturbance by a sphere in a point-source diffusing plume developing in grid-generated turbulence. Special concerns are given to the effect of the distortion of the mean stream near the forward stagnation point on the diffusion. Some results from statistical processing of experimental data are given. It is found that because of the strong distortion of the mean stream, the molecular diffusion in the vicinity of the stagnation point is accelerated to a great extent, and as a result, as the stagnation point is approached, the conditioned probability density function for near-zero concentration shows a remarkable slump. This result is explained qualitatively with the help of the pdf budget equation. A new concept, "smeariness", is defined and used to explain the experimental results effectively.
