can Pipe(TL) is used with Pneumatics

1 view (last 30 days)
As I want to Measure Pressure drop in Pipe considering Parameters like compressibility so for that can I use Pipe(TL) as segmented/discretised models so I can compare pressure drop in segmented pipe.

You cannot do it directly. The Pipe (TL) block uses the Thermal Liquid domain, which is different from the Pneumatic domain.
However, you can make your own segmented pneumatic pipe approximation by creating a repeating pattern of "Pneumatic Resistive Tube" > "Constant Volume Pneumatic Chamber" > "Pneumatic Resistive Tube" blocks.
Pretty sure that's how the pipe blocks in other domains (hydraulic, thermal liquid, two-phase fluid) do it, anyhow.

Sir As I gone through Support File of Pipe (TL) and some text is as below It uses Darcy Weisbach Law which is applicable to Pneumatic also and I want account same like pressure losses and heating due to viscous friction and conductive heat transfer through the pipe wall.
As I insist to use Pipe(TL)Because it also includes heating due to viscous friction.
From Support File Description of PIPE(TL) The liquid experiences pressure losses and heating due to viscous friction and conductive heat transfer through the pipe wall. Viscous friction follows from the Darcy-Weisbach law

The Pneumatic Resistive Tube block uses this same friction law, and the Constant Volume Pneumatic Chamber block has a thermal port that you can use to model heat transfer.
So what I mentioned in my first answer should work to recreate the same and allow it to connect directly to other Pneumatic domain blocks.
