I am working on a project based on the simulation of water splash generated by the rear wheel of a bike.
I want to simulate the trajectory of water caused by the wheel.
I started with following setup and boundary condition

A wheel geometry enclosed by two enclosure both cubical box based on hex dominant and tet dominant mesh. I used tet dominant mesh for enclosure near to the geometry as the flow around the wheel is of major concern.

Boundary included:
Ground : moving along x-axis
inlet : velocity along x-axis for air
wheel walls: set to rotation about the origin along z axis
outlet: at gauge pressure

Model used : VOF phase 1 : air phase 2: water, Implicit method

Result obtained:

I used pseudo transient method to get the above result.
I don't know my simulation result are able to capture any physics of such problem. Is there any better approach to solve this type of problem?
I read about mrf approach but as my problem involves both translational and rotational effects I am not sure mrf approach would be good for this problem.

yeah .. but there is no details of setup of anything in the link you provided. can someone provide me any better reference?
