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.
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?
