Abstract

Some numerical methods are briefly described for determining vertical diffusion coefficients as a function of vertical coordinate in a turbulence vessel where there are no net velocities. It is planned to use this turbulence vessel and these numerical methods to study in detail the mechanics of diffusion of a substance (analogous to oxygen) which is absorbed at the free surface. A hot-film anemometer is to be used to make direct measurement of turbulence parameters affecting the diffusion process. The anemometer has been calibrated in water which was in solid body rotation. Some of t>he difficulties experienced with the hot-film sensor and the corrective measures which were used are discussed. Preliminary diffusion tests have been made in the turbulence vessel where turbulence is generated by vertically oscillating screens made of expanded metal. Some values of the vertical diffusion coefficient have been calculated from the data for two of these preliminary runs. Plans call for making more detailed diffusion studies and for making direct turbulence measurements in studying surface reaeration.
