Numerical Study on the Effect of Port Orientation on Multiple Inclined Dense Jets

Wastewaters are commonly discharged into the seas and oceans through multiport diffusers. Accurate prediction of complex interactions diffusers with receiving water bodies is significant for optimal design outfall systems has yet to be fully illuminated. In current study, mixing dilution characteristics multiple inclined dense jets studied using a three-dimensional numerical simulation. The Launder, Reece, Rodi (LRR) turbulence model employed perform simulations, predictions compared against available experimental data. results indicate that LRR promising tool study from diffusers, it can provide more accurate behavior than standard re-normalization group (RNG) k-ε models. further evaluate compare dispersion capabilities uniform non-uniform jet orientation horizontal, as novel idea. comparisons demonstrate middle discharge may have longer trajectory (7% 5% increase in terminal rise height impact point distance, respectively) therefore higher rate (14% dilution) when its adjacent disposed different angle, discharges. outcomes favorable applications involving dilution.
