| Abstract |
A jet issuing close to or at the free surface is called a surface jet. They represent the discharge pollutants into larger bodies of water. The interaction of the jet with the free surface gives rise to structures that dominate the mixing and transport of scalar species. There are several experimental studies of surface jets at low as well as high Reynolds number and Froude number. These studies have resulted in some important information regarding the velocity field of the surface jet. One of the main reasons for studying surface jets is to understand their scalar transport characteristics. However, there is no significant study of scalar transport properties of the surface jet reported in the literature. In this study a direct numerical simulation of surface jet at a Reynolds number of 4,420 and Schmidt number 1.0 is performed to investigate the scalar transport. In the absence of any experimental study of scalar transport the results are validated through the grid independence study and comparing velocity field with the experimental data of Gholamreza-Kashi et al (2007). Here the mean and root mean square (rms) distribution of scalar species will be presented along with the influence of large-scale coherent structures on the scalar transport. |
