We are trying to design an impeller which takes flow from a full pipe (DN250) and forces it in to a rotational motion. The flow leaving the impeller proceeds axially in a 400mm diameter rotating drum. This is actually a “water ring” with an air column in the middle. This means that the flow in...
We have a device which has a 400mm diameter drum rotating from 400-800 rpm. Inside the drum there is a water ring, which thickness varies depending on flow rate, drum rotational speed and pressure. We have measured the thickness of this ring (actually the air column) with a capacitive type...
