Hello, everyone.
I'm looking for tips and tips to perform a simulation on ansys' fluent module.
the configuration to be analyzed is as follows: a generic form excavation is made on a plate that rotates around a point with an angular speed; the plate is inserted in an isolated case so as to generate, with its motion, a difference of pressure between mountain and valley of the excavation... in practice its function is that of dampener.
Now... the main problem lies in the schematization.
I had thought of making the problem one-dimensional (by hindering rotation) and therefore imagining the flow as if it were enclosed within a conduct that meets in series abrupt shrinkage and abrupt enlargement. This, however, seems to me an excessive simplification as I cannot consider a flow at constant speed along the section precisely because this speed varies with the distance from the center of rotation of the plate. the advantage of this method should be that I avoid introducing moving objects... What I have never done:
alternatively it would be necessary to model the real system and then to predict a fixed external case and a moving rotor immersed in the fluid.
If in the first case I had doubts about the imposition of boundary conditions, with the second solution I should just start from scratch! :frown:
I hope I have explained the physical pattern well and even more I hope you can/want to give me a hand. I am working on a project for a matter and this simulation would be cherry on the cake :wink:
Thank you all!
