You can run static analysis on your new turbine design. Check on the static torque coefficient, Ct on every rotor angle. The positive value/ higher of Ct shows good turbine starting capability.

FLUENT CFD can do that given the cad geometry has no problems

You can use SimScale

The number of blades is an important aspect in the design of this technology. The number of blades determines not only the aerodynamic performance, but also the rotational speed characteristics of the turbine. Turbines with low number of blades may have high rotational speed while turbines with high number of blades have low rotational speed

Pranay Vijay Nimje try to do the CFD simulation and prototype testing. For CFD simulation ANSYS or Solidworks. Please follow the video tutorial attached
