Hi All,
I am trying to calculate the pressure drop of a flow between parallel plates. The fluid will be helium at 5 K and 1.3 bars. The plates are 100x220x0.6 mm and 1 mm spacing. They will operate in the turbulent region. It is a test for a heat exchanger. Does someone know the relations for...
Thx for the help allready provided!!
The first thing I did was to get the information from the supplier but they only have the pressure drop values at one state where I am (trying to) scaling from.
The thing is I put all my piping & HE (>1000) in a model where I used a electrical-equivalent...
Hi All,
I am building a pressure drop model to calculate my maximum mass flows through a large network of piping. Now there are a few Heat exchangers implemented from which I have no information on how they are constructed. I only get the pressure drop values that are measured at given...
Dear Quark,
Baseline design and information are available on www.cern.ch, for Vacuum info go to intranet, find EDMS (document server) and find the LHC-ACR/vac group there everything is listed, even to the public...

Hi Guys,
Thanks for the help allready it has got me thinking. I yesterday adjusted the finite differance model with some assumtions and split it up in different temperature ranges. I am now plotting 22.000.000 points but split up so the waiting is not so hard.
For the lumped model, my...
Hi all,
I am working on a cryogenic distribution line (helium) and am analysing the time needed to get the thing down to nonimal conditions. I am using a lumped parameter model (global guess) and a Finite differance one for the temperature profile. Because of large derivatives in the in the...
