Shear force on rotating disk

Squid · April 12, 2010, 09:06

I'm new to floworks and I am modelling a Tesla turbine on floworks but cant get it to show the shear force that is acting on the disk.

I have a really simple model of an inlet that leads the fluid between 2 disks that I have spinning at a certain rpm and there is a hole in the centre of the disks for the water to flow out off. I can get do a surface plot or a 3D plot to show the pressure at different parts of the model but I am unable to make it show the shear force that is acting on disk.

Is there anyway to do this?

Any help would be much appreciated.

shear force can be viewed in the latest version 9.4 and for that you need to request this output in the Output tab. I think the option is called "Critical shear stress"

Squid,
You say you are "new to floworks". Do you mean to be in the FLOW-3D forum? If you're using Cosmos Floworks, the users here won't be able to help.
