The gravity would be constant if the rotation was constant. No sure what you mean by 'no friction'. Friction against the wall?
- marcosdumay 5y ago> The gravity would be constant if the rotation was constant. Hum... No. The gravity reduces linearly with height. And yes, friction against the wall.
- hermitcrab 5y agoI was referring to gravity being constant at the surface over time. I'm not convinced friction with the wall is going to result in any additional air loss. There is no 'upward' (towards the top of the wall) force component.
- ncmncm 5y agoYou keep the walls in permanent shadow. Convection keeps the air near them moving downward.
- marcosdumay 5y ago> There is no 'upward' (towards the top of the wall) force component. Friction ensures that whatever air reaches a high altitude near a wall tends to stay at that altitude and spread again on the lower gravity. The difference in pressure between this higher place and a lower one bias the movement up, there is no upward force component on the dynamics of any few components you can choose, it's emergent.
- hermitcrab 5y agoI haven't heard of this effect. Do you have a reference?
