Re: labyrinth seal leakage anlysis using fluent4.23 -if any bench mark problems pls send it to my addres
(1). For us to help you, you need to state the kind of difficulties first. (2). The geometry of a labyrinth seal is very simple. And it is 2-D axisymmetric. (3). You can specify the inlet velocity as the boundary condition. That should be good enough to obtain the flow field through the labyrinth seal passage, and then you can obtain the pressure difference between the inlet and the outlet stations. (4). The only difference between 2-D and 2-D axisymmetric is that, in the labyrinth seal case, one of the walls is rotating. This could be the seal itself, or the casing, depending on the design. (5). If the difficulty is related to the use of a particular code, you will have to find the solution from the person who wrote the code first.
