- Abstract
Although several experiments have been done on inclined dense jets in shallow water where inclined dense jet interacts with the water surface, the jet trajectory and minimum dilution at the return point (Sr) and water surface (SS) have not been generally formulated and reported. In this paper, new evolutionary-based models are developed to predict variables describing jet trajectory and dilution, including the non-dimensional horizontal displacement of the return point (xr/D), non-dimensional horizontal displacement of the minimum surface dilution point (xs/D), dilution at the return point (Sr) and minimum dilution at the water surface (SS). These parameters are essential in brine discharge system design. Two sets of experimental data are applied to develop and evaluate the models, and the model networks are optimized using gene expression programming (GEP). The mentioned parameters serve to compute dilution and displacement at the return point and water surface as a function of discharge angle (θ), non-dimensional ambient depth (H/D) and jet densimetric Froude number (F). Partial derivative sensitivity analysis is also carried out to examine the effect of each dimensionless input variable on the target parameters. The explicit equations and pseudo codes reported facilitate easy estimation of the trajectory maximum impact point distance as well as dilutions for dense jets at different angles from the horizontal.
