labyrinth packing
At the entrance of 1000 Pa. medium air
The rotation of the shaft 10 000 rev / min.
The clearance between the shaft and the labyrinth 0.15 mm

Determine the leakage of air through the maze.
Placed at the output of 0 Pa.
In solving are too little speed honey shaft and labyrinth.

Hi, 

 

Please could you be a little more specific about the problem? I understand that you have 1000pa on one side and 0 on the other, the unit is rotating and you have a small clearance.

 

Do you have a very good mesh through that small gap?

 

What do you mean by 'In solving are too little speed honey shaft and labyrinth' ?

The situation is this.
For large shaft speed of the maze thrown oil.
Necessary to analyze and optimize the design of seals labirintnogno

OK, those help. What about the mesh on the cut-plane? You need a good 4-5 elements though each of those gaps ideally.

 

What is your actual question, are the results not what you are expecting to see?
