Hi PF!
I have an experiment where a wedge about 160mm long is in microgravity. I withdraw silicone oil from the wedge at a relatively slow rate (no turbulence). Since the wedge angle is small, a lubrication approximation is made. Inertia is shown to be low.
I want to simulate this flow. When considering a contact angle model to employ, I implement a constant contact angle model equal to the static contact angle, 0 degrees. How do I know if this is valid, or if a dynamic model should be implemented?
