Need some help on flow simulation here. Beginner students in solidworks here

Dear all,

I am new to solidworks and currently needed to learnt that in my country (singapore) polytechnic.

I like to create a hollow cylinder and having a rotational flow inside the cylinder.

What i do in my solid is i create a extrude cut cylinder having hollow inside. Next i create another lid part. Then i open up assembly file and mate all together.

I am only able to create flow from the bottom lid to top lid. but unable to create rotational flow.

Any helps advice is greatly appreciated.

Thanks in Advance.
