I am running a mixing simulation in React between hydrothermal fluid (350C) and seawater (2C) and am wondering how GWB determines temperature. I mix 1000 parts seawater into 1 part hydrothermal fluid and get to 5C - this is good. It appears that temperature changes linearly with mixing. Does React account for the nonlinear dependence of temperature on heat at high temperatures as density changes? I do not see anywhere in the database or the output that it keeps track of heat capacity or enthalpy, although I see that it tracks density of the mixed fluid.
Thanks for your help.
