ask for advice

Dear Friends,

I want to know effect of the diameter of the cylinder on the movement of the yarn in cylinder.

The cylinder has two outlets and one inlet. From inlet, compressed air runs into the cylinder and acts on the yarn. In simulation, there is no yarn.

If I changed the diameter of the cylinder, the distribution of the airflow inside cylinder and the property of the yarn will change. Which parameters I should compare in these two cylinders, pressure? temperature? total pressure?,,,,,,,

Could you give me some advice?

Thank you in advance

Eric
