<p>Mohamed,</p>
<p> 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.</p>
<p> 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.<br>
</p>
<p>kind regards,</p>

<div><br>
</div>
<div>I would like to mix two streams of fluids. the temperature
of the fluids are known. the flow rate of the first stream is
fixed. I need to take part of the second stream to mix it with
the first stream in order to reach to some specific
temperature values. Could you please tell me how can I do
that. Any help will be appreciated </div>
