Dear all,

I would like to simulate air injection in axial fan. The mesh for rotor and stator domain was generated using turbogrid. Now i wiuld like to put injector to inject air at the inlet. How do i proceed in such case. My confusion is
1.How to model and mesh this case. Like freeze the injector in inlet domain and what should be the length of injector for simulation?
2. BConditions for fan as inlet mass flow and total pressure outlet. But what about injector ? The mass flow rate is known to me.
3. If i have even number than shall i take blade passage accordingly and if odd number of injectrors than do i use full domain?


Please guide me for the same

Thanks
