STAR-CCM+ Tutorial | Multiphase Flow in a Gearbox | Part 6 - Results and Visualization | Advanced

In this STAR-CCM+ tutorial, we set up the classical multiphase flow around a gearbox and simulate oil splash lubrication using a rotating gear train.
You will learn how to build the model from scratch, choose suitable multiphase settings, and visualize how the oil distributes inside the gearbox.
