Two-Phase fluid - Weird Temperature peak
2 views (last 30 days)
I am trying that really nice SimScape two-phase fluid library.
I am simulating a double acting steam free piston.
It is running without errors (most of the time, depends a lot on the valve pipe diameter I set ...), but the weird thing is when I increase the reservoir volume, the temperature suddenly shows really high peak in the beginnnig of the stroke (like if it was overheated steam).
Which is pretty surprising since I would expect a rise of pressure when the piston compress the fresh steam, not temperature ?
And the peak to be lower and lower when volume increase, but it is the contrary happening.
Any idea why is it happening ? It doesn't seems right to me.
