Great. The helium presents more of a problem at joints and valves really.
The mass flow rate will be around 500 kg/s in some areas and as low as 12.2kg/s in others. The density varying between 4 and 7 kg/m^3.
The worst case is 500kg/s, 1200C, 80Mpa, 7kg/m^3 and 100m/s flow.
I can't really...
True. I will certainly have to look into ceramic lined pipes. Unfortunately the project is theoretical at the moment so I can not arrange to have an engineer specialising in this area come out.
How is the ceramic attached to the inner of the pipe? This is the point where the stresses are...
Thanks for the reply. I did think aboout this sort of method.
Could you possibly point me towards the sort of materials used for the inner layer and how they are attached to work as a thermal buffer but not to take any stresses caused by the high pressure.
The conditions are extreme...
Hi everyone,
I have been trying to find some materials that could be used for very high temperature piping but have been struggling quite a lot. I have been looking at stainless steel alloys mostly.
The specs are really tough:
1200 celcius of helium at 80MPa. My main concern here is...
Hi everyone,
I am wondering if the heat equation is valid for compressible fluids like air. This is assuming constant 100% humidity.
If it is not then how close is the appoximation.
The model assumes that heat moves through an array of air only by conduction. At the moment I use a...
Thanks, I will try it now
It didn't work. The only way I have been able to do it is by putting a new for loop in that runs a variable up the array and use that to work up the array but it looks a lot messier than it should be...
Hi everyone,
I am having a bit of a problem with Matlab. I am currently using a finite difference mesh to solve the heat equation across one spatial dimension - x and time. I had an water array with depth and time and a boundary condition given by heat transfer equations which set the top...
