We are trying out a simple CFD model in MSC SCFLow of a simplified axial fan on a shaft sat within a cylinder. In order to determine the output velocity, is it worth having the fan rotate within the simulation with the boundary conditions on the flow input set to ambient with the speed of the...
If I had a cold trap cylinder that had a internal surface area of 1 meter squared, the trap material was stainless steel that was 10mm thick. The chiller was -60 degrees c on the outside of the trap. For argument sake, the material entering the trap is water vapor. How do I calculate the...
I have an interesting problem that a few of us in the office have been struggling with.
You have a simple water storage cylinder that is heated to produce steam. It flows through 4" pipework to a pump some 200 meters away and is then exhausted into atmosphere. Trying to work out what the...

I have an oil filled systems that is free from air, and at atmospheric pressure. As the temperature of the surrounding environment changes, the oil expands and contracts. I have designed an expansion cylinder into the system that allows for this change in volume which is a cylinder that caps...
I have a mathematical problem…
I’m trying to work out what the cross section of a Torus would be once it has been stretched over a shaft. So, for a given temperature the volume of the Torus would be the same no matter what amount of stretch you impart on the inside diameter. So the volume of a...
Hi all,
I'm about to start the manufacture of a large ceramic disc (263mm in diameter) which will currently be turned on a lathe. The disc has an inner bore as well a bit like a large scale polo mint. The bore diameter is around 95mm.
Can anybody tell me what they think the best geometrical...
I have currently had some small parts fail during a vibration test and it's more than likely that the shock part of the test that made it fail.
I've come up with some new ways to protect this part, but testing these methods will be very costly. Therefore to mitigate this risk i want to devise a...
