“…E 20 was significantly affected by the Fr and the ratio of the water cross-sectional airflow to the duct cross-sectional 64 . Another piece of literature by Puri et al 65 demonstrates that an increase in discharge and oxygen transfer has accompanied a rise in Fr . The outcomes of the present study also confirm that E 20 and Fr are directly related.…”

Dissolved oxygen (DO) is an important parameter in assessing water quality. The reduction in DO concentration is the result of eutrophication, which degrades the quality of water. Aeration is the best way to enhance the DO concentration. In the current study, the aeration efficiency (E20) of various numbers of circular jets in an open channel was experimentally investigated for different channel angle of inclination (θ), discharge (Q), number of jets (Jn), Froude number (Fr), and hydraulic radius of each jet (HRJn). The statistical results show that jets from 8 to 64 significantly provide aeration in the open channel. The aeration efficiency and input parameters are modelled into a linear relationship. Additionally, utilizing WEKA software, three soft computing models for predicting aeration efficiency were created with Artificial Neural Network (ANN), M5P, and Random Forest (RF). Performance evaluation results and box plot have shown that ANN is the outperforming model with correlation coefficient (CC) = 0.9823, mean absolute error (MAE) = 0.0098, and root mean square error (RMSE) = 0.0123 during the testing stage. In order to assess the influence of different input factors on the E20 of jets, a sensitivity analysis was conducted using the most effective model, i.e., ANN. The sensitivity analysis results indicate that the angle of inclination is the most influential input variable in predicting E20, followed by discharge and the number of jets.

“…Research studies pertaining to oxygen transfer through conventional circular plunging jets have been extensively documented in the literature. Numerous research have been done on the subject, including those by Ahmed [9],Van de Sande [10], Bin and Smith [11], Tojo and Miyanami [12], Tojo and Miyanami [13], Bonsignore et al [14], and Puri et al [15]. However, there is a dearth of research on the oxygenation performance of plunging jets with non-circular geometries.…”

Plunging jets are popular for aeration in wastewater treatment plants due to low energy needs. In the present study, square jets were evaluated to determine their effectiveness in providing aeration efficiency by plunging jets in an open channel flow. The study seeks to add to the existing knowledge and provide insight into the performance of single and multiple square plunging jets in wastewater treatment plants. Passing a water sample from the pool through an open channel, via square water jet(s), has shown that variables such as a higher number of jets, and discharge have a significant impact on aeration efficiency (E20). The findings demonstrate that the increase in E20 was found to be 85.22% to 117.6% with Nj=64 over the single jet when discharge was varied from 3.41L/s to 4.75L/s, further affirming the remarkable effectiveness of plunging jets in promoting aeration in open channel flows. Furthermore, it was observed that Fr. No. is the parameter that has the most impact on calculating E20 with correlation of 0.95311.

“…Experimental studies were thoroughly examined and summarized in a detailed review by Bin and Smith . Various experiments have been conducted on the oxygen transfer achieved through plunging water jets. − It is clear that there is considerable interest in the topic of air–water–oxygen transfer through the employment of plunging jets, and as such, it is a topic that continues to get a lot of interest from academics in the field.…”

Since soft computing has gained a lot of attention in hydrological studies, this study focuses on predicting aeration efficiency (E 20 ) using circular plunging jets employing soft computing techniques such as reduced error pruning tree (REPTree), random forest (RF), and M5P. The study undertaken required the development and validation of models, which were achieved using 63 experimental data values with input variables, such as angle of inclination of tilt channel (α), number of plunging jets (J N ), discharge of each jet (Q), hydraulic radius of each jet (HR), and Froude number (Fr. No), to evaluate the aeration efficiency (E 20 ), which served as the output variable. To evaluate the effectiveness of the developed models, three different statistical indices were used such as the coefficient of correlation (CC), root-mean-square error (RMSE), and mean absolute error (MAE), and it was found that all of the applied techniques possessed good forecasting ability since their correlation coefficient values were greater than 0.8. Upon testing, it was discovered that the M5P model outperformed other soft computing-based models in its ability to predict E 20 , as demonstrated by its correlation coefficient value of 0.9564 and notably low values of MAE (0.0143) and RMSE (0.0193).
