<p>Ilyas,</p>
<p> I am not sure whether you are asking how you define a coupling
flow of air between two zones or how the quantity of flow is
calculated.</p>
<p><br>
</p>
<p>To define a flow in TRNBuild, click on an ADJACENT wall and you
will see a field appear below where you can define the coupling
flow. Defining a flow creates a flow only in one direction. If you
want equal flow in both directions (ie mixing flow) then you'll
need to find the same wall in the adjacent zone and define the
flow in the opposite direction.</p>
<p><br>
</p>
<p>The most rigorous way of calculating the quantity of flow between
zones is to use either TRNFlow or CONTAM/Type97. Both of these
models require that you describe the air flow paths between the
zones.</p>
<p>kind regards,</p>
<p> David</p>
