Mohamed, There are two ways that you can do it. If you are trying to model a tempering valve (a device that prevents one stream of liquid from overheating by mixing in some colder liquid) then you can use Type11. Look in the 04-MathematicalReference manual and it will give you an example of how to model it. If you have a more general case and you want to know in what
ratio to mix the liquids to obtain a certain mixed temperature
then the ratio can be computed based on knowing the temperatures.
Once you solve the mathematics, you can then implement them as an
equation in your input file. Use the ratio as the control signal
to a mixing valve model. kind regards, David
