Calculate the R no. for both nozzle and inlet. Based on the maximum R no. u should choose the model. If it is below 2000 u could choose Laminar other wise turbulent model. for low range 3000-10000 S-A model is the best as it takes less comuptation time, other wise k-e model.

Just have a look Fluent Manual Ch 10.
