gas mixing through a T joints
gas mixing through a T joints
(OP)
Hellow,
Looks like here is a good place to presnt my silly question. Thank you in advance.
I'm currently "hybriding" two gas flow with a T joint. Both in small flow rate, so the diameter of the pipes is about half centimeter.
the two inlets are managed with separate mass flow controllers. which have been setting to following values:
in 1 in 2
case 1: 150sccm/m 50sccm/m
case 2: 100sccm/m 100sccm/m
case 3: 50sccm/m 150sccm/m
] [
]in2[
] [
-------------] [-----------
inlet 1 outlet
-----------------------------
My question is would any of the inlet flows being surpressed by another one, if we could assume the mass flow controller is constantly outputing the presetted value. especially when the inlet2 is 150sccm/m
regards

Believe buffer should be necessary to overcome that. Outlet pipe can serve similar purpose, if having sufficient lenght/diameter.
Did you consider installation of turbulator that would speed up and improve mixing?

I run the flow for hours, so some seconds is not a problem. As far as a stable flow will be obained in the end.
I forget to tell the pipes is connected to a tiny chamber which has a exhaust. So the consumption is always there.
regarding the buffer, I think it's like a chamber the two inputs can go in and has a outlet. I guess it can lighten the "conflict" of two flows, so they can flow in the defined rate even at transition periods.
If anyone agrees what I said above. I shall do it. By the way, where can I buy such a chamber/bottle.
