Abstract

Experiments were conducted to investigate the effect of jet shape, inclination, velocity ratio and initial concentration on the characteristics of side polluted surface water jet in open channel with two different angles of inclination to mainstream direction. The polluted water is prepared by adding sodium chloride with different concentrations to fresh water. The initial jet velocity is varied to cover a range of velocity ratio R from 3.30 to 10.30. For each velocity ratio, the solute concentration is changed to take values of 800, 1050, 1440, 1780 and 2320 ppm Centerline jet trajectory, velocity decay and dilution of polluted water are measured. Velocity is measured by a calibrated current meter while the jet coordinates and water depths are measured using point gages. Samples are taken from the jet centerline to measure the jet concentrations. The concentrations are measured using 4510 conductivity meter. The factors influencing the problem are normalized with the help of dimensional analysis principle. The analysis of the results revealed that the geometrical characteristics of a polluted water jet in cross-flow, the decay of velocity and dilution of pollution concentration are mainly depending on the studied parameters. Equations have been developed from the correlation of the experimental results.
