I need some advices to start to solve some problems about fluid motion in a conduit.

The problem domain is shown below: a conduit with some obstacle of different geometric properties.

Motion of a fluid in a conduit

The fluid is a "real" and viscous, the viscosity is very high in relation to speed (low speed, very high viscosity). The fluid is in pressure and comes from the blue arrow, I need to know the "speed or amount" of fluid in each output (red arrows). I don't need a real-time simulation.

How can I approach this kind of problem?

  • $\begingroup$ I think that you can use a CFD software like openFOAM or Fluent. Have you checked those? $\endgroup$ – nicoguaro Jan 27 '16 at 20:53
  • $\begingroup$ I'm checking openFOAM thanks. I'm trying to implement this in a my application. $\endgroup$ – blow Jan 27 '16 at 21:07
  • $\begingroup$ Are you interested in programming your own solver? $\endgroup$ – nicoguaro Jan 27 '16 at 21:11

    $\begingroup$ I think you can invoke Bernoulli's equations on this problem. I don't think there is an need for numerical simulation (unless I'm missing some additional information here). $\endgroup$ – Paul Jan 27 '16 at 21:54

    $\begingroup$ You say low speed and high viscosity, but what's the Reynolds number based on channel length and inflow velocity? $\endgroup$ – Bill Barth Jan 27 '16 at 22:12
