I am not entirely clear on whether you are controlling the total
amount of flow going through the solar collector or whether you are
trying to compute the fraction of the collector's known outlet flow
that you need to mix into your exhaust gas stream in order to
achieve a desired mixed temperature. If you are trying to control
the outlet temperature of the collector, there are collector models
available that will internally compute the flow rate required to
achieve a desired temperature. If you have to known air streams that
come together to achieve an outlet temperature, use Type33 on each
air stream to get the air stream enthalpies then use some equations
to back-calculate the quantity of air that you need from each stream
in order to get the desired temperature. Don't forget about the
latent effects when mixing!!<br>

<div>Dear users</div>
<div> </div>
<div>I want to model a flow mixer where hot air from a solar
reciever will be mixed with exhaust flue gases from the gas
turbine </div>
<div>before entering a HRSG , i have tried using a tee piece for
mixxing the flows but the outlet temperature of the mixture is
below</div>
<div> the needed temperature which is the gas exhaust temperature
, can i use another component to keep the temperature steady
while controlling the flow rate.</div>

<div>Thanks</div>
