Evolution of a Negatively Buoyant Jet in the Near and Intermediate Field
Author
Summary, in English
A Matlab code developed describing the lateral spreading and centerline dilution of buoyant jet and plumes for near and intermediate field was developed. The model produces results in acceptable agreement with data and observations, even though some improvements should be made in order to give the correct weight to the bottom slope parameter and to reduce the need for user calibration. An overall assessment of the CORMIX software behavior cannot be made; in our case (i.e. small scale) the software was not giving simulation results that reproduced the data.
This study has limited result for only 16% bottom slope and 30 degrees inclination. Concentration was improved with the bottom slope by 10% than the horizontal bottoms and improved by about 40% with bottom slope together with inclination of 30 degrees. The suggestion in the practical applications concerning desalination brines and similar discharge of heavy wastes is to have inclination and bottom slope together.
