[TRNSYS-users] Mixing two fluids

[David BRADLEY via TRNSYS-users]

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
