What if we disregard the solid walls and the flow on the outside of the two discs and are just looking at the flow in between the rotating discs, nowhere else. In this case the concept of conservation could be applied to the discs and fluid, correct?
Now the model is simplified to exclude any...
Is there a possibility that these vortices could somehow cause the fluid to speed up near minimum fluid speed (aka maximum disc speed) or would the tangential force from free flowing gas and tangential couple from gas vortices create the same outcome that is speeding up the rotation of the disc...
In your opinion, does it make sense that the flow velocity could increase due to a dominate momentum?
I am starting to think that the author is considering flow velocity to increase after its minimum value due to the increase in pressure at this minimum point, when the flow slows down to its...
If I were to blow a finite amount of air into the turbine and no more, and then say that my control volume contains the discs and the finite amount of air, could I apply the conservation of momentum to that cv?
I believe that in this cv, the air transfers its momentum to the discs via shear...
I am sorry I should have included this in the main message. When I say disc I am referring to the discs within a tesla turbine. I have attached an image of the discs, the air enters at the outer radius r2 and exits the turbine through the central exit at r1.
The specific paper that I am...
The supersede part makes sense to me when considering the angular momentum of the entire system. But could you explain how momentum transfers in this scenario? My understanding is that the momentum from the air flow transfers to the disc via friction, thus slowing down the flow to a minimum...
I have a disc that is rotating due to air being blown at its outer radius. The incoming relative velocity of the air is high, therefore the effect of friction supersedes the effect of conservation of angular momentum. The tangential portion of this velocity decreases due to the friction as it...
