HI,

Been trying to use COMSOL to simulate 2D the velocity and pressure profile in a tube. I have vary the inlet pressure and keep the outlet pressure constant at 0 bar.
Is the time taken for the flow profile to fully develop or reach steady state decreases with decreasing pressure or it with increase with decreasing pressure?
Whats the theory behind this?

Hi Julian arch,

I recommend you to go through Darcy's law or Darcy's equation for laminar flow.

Also, i suggest to go through below book

M.H Bao- Sensors and Actuators

I hope below PDF will help you.

I would suggest you to post your question on comsol community forum, i think hardly anybody here uses comsol.
