How to add heat in my model to compensate pressure drop

4 views (last 30 days)
1) As my Purpose is to find out the losses/pressure drop in compressed air transporting pipe, As for same I used example and added pneumatic resistive tube and my code is working. 2) And Second aim is to add heat to compensate this losses now there is not getting direction - how to start. </matlabcentral/answers/uploaded_files/38636/Code%206.png>

There are two blocks in the Pneumatic Foundation library that allow you to add heat to the system. These are the Constant Volume Pneumatic Chamber and the Pneumatic Piston Chamber blocks. Both blocks have a thermal port, labeled H, which can connect to Thermal domain blocks.
If the heat is added to a variable volume of gas in an actuator, then you should use the Pneumatic Piston Chamber block. If the heat is added to a constant volume, e.g., a pipe, you should use the Constant Volume Pneumatic Chamber.
For the latter case, a pneumatic pipe can generally be modeled using the construct in the image below. It's very common to do this.

a query Is here as I m changing my sensor position like after 1st resistive tube or after second resistive tube then as getting different result not getting fundamental for same about position or I am doing mistake in position of constant volume pneumatic chamber<</matlabcentral/answers/uploaded_files/40579/Model_21_11_15_2.jpg>>

Hi Sir There is no rise in Pressure of air again after adding heat in system
