How to make this circle shape SMOKE with a hole?


I was trying to do it but i cannot make a hole for the smoke. Here is my blend file so please take it and if you can improve so there is a hole than i would be grateful


i was also trying to make collision but i failed as well with that

Ok. I was playing a bit more with that now and found that setting resolution divisions up to 200 makes that hole for the smoke. But still whould like to here your advices guys

Create circle
edit mode -> select all -> extrude -> escape -> s 0.8
object mode -> quick smoke
smoke settings
up the resolution to 64
high resolution to 2
