    Graduate Prandtl number of a g/l mixture (Ethane at phase transition)

    Hi Chet, I get the idea: If the heat transfer coefficient is much higher on one side than on the other I can neglect its contribution to the thermal resistance. However, The Methane/Ethane side is not a non-condensing gas, it's a cryogenic liquid. Will the heat transfer coefficient of the...

    Graduate Prandtl number of a g/l mixture (Ethane at phase transition)

    Is it a problem to calculate a heat transfer coefficient, or the prandtl number, or the specific heat of a fluid during phase change? Any of those would answer my question.

    Graduate Prandtl number of a g/l mixture (Ethane at phase transition)

    Hi Chet, I'm just trying to make a preliminary calculation on a LNG gasification heat exchanger. I tried to find a numerical solution for my problem but I am interested in finding the local heat transfer coefficient in the region where Ethane undergoes a g -> l phase change. Im calculating for...

    Graduate Prandtl number of a g/l mixture (Ethane at phase transition)

    I have a problem in finding the heat transfer coefficient of a heat exchanger in which Ethane undergoes a phase transition. I would like to find the Prandtl number of Ethane in the phase transition region. So far I thought I would use the following: Pr_av = x * Pr_g + (1-x) Pr_l Pr_av =...
