Fluid dynamics question I need answered regarding gasses.

I have a question about flowing argon into ambient air through a 6mm nozzle at a low flow rate.
I need to have the comparison shown between internal spirals to force a “twist” or rotation to the argon as compared to a straight nozzle with 0 twist.
I’m looking to improve the argon’s flow to maintain a straight exiting of argon from the nozzle tip as possible.
If forcing a rotation in argon does improve the trajectory then finding the optimum degrees of twist would be beneficial.
I’d like to be linked to some previous papers that confirm the answer and if it’s helpful then some diagrams to show the results with and with out twist.
