- to add the vertical wall normal to the flow at the section of the rotation axis, in order to reduce the gap between the wheel and the lateral walls, while maintaining the channel wider than the wheel, in order to enable the filling and emptying process;
- to perform a mesh independence analysis while maintaining low values of ;
- to assess other turbulence techniques and associated models (particularly the model for RANS already implemented in the solver);
- to incorporate the continuous calculation (at each time step) of torque and shaft power into the solver.
