    Parallel plate pressure drop

    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...

    Scaling Pressure drop in Heat Exchanger

    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...

    Lumped parameter model

    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...
