FIG. 4.

The graphical user interface (GUI) that was developed as the educational tool. The parameters affecting the effectiveness of mixing, including five geometrical parameters and the flow rate, are chosen from the left tab. The ML model predicts new results when these parameters are altered. The GUI includes two separate sections for Newtonian fluids and non-Newtonian fluids. Users enter their desired parameters in the appropriate sections and upon pressing the “Calculate” button, the predicted mixing index result based on the ML model appears as percentage next to this button.
