Hi,
I needed help regarding where and how I could enter the acoustic impedance (density x speed) for a material in ANSYS.
I know there is a tab under Appply loads>Fluids>impedance.....But if if I am not mistaken, the value to be entered there is between 0 and 1.
So can anyone tell me if I have...
Hi Guys,
Im trying to model a part of the windshield in an impedance tube to check the noise reduction across it. When I model it in ANSYS, the noise reduction seems to change with the area of cross section. But in reality, no matter what the area of cross section is, the noise reduction should...
Hi guys...
I am trying to model a porous material in ANSYS 12 and it requires to inputs - BIOT CONSTANT and FLUID PERMEABILITY. Any idea on how I can calculate these two values for my material (PVB). This doesn't have these values readily available. So i will have to calculate it.
Any help...
Hi Guys,
I am trying to model a tube in ANSYS which has a sample sitting in the center. I basically want to measure the noise reduction across the sample inside the tube. I need some help and ideas in modeling it.
Any Help will be appreciated

Hi...I am trying to model an impedance tube with a plain glass sample inside using ANSYS which is good for high frequencies. This means that the radius is small. I have a thickness of 4.8mm for the sample. I am having problems when i model this small sample (bigger cross sections work). I get...
I am trying to model a tube through which air passes and at the end of the tube is a porous element. ANSYS 12 has some porous elements in its database.
Can Anyone tell me how we can model this particular porous structure? ....
As in wat all properties will be needed and if u know the procedure...
