Undergrad How does a fluid behave inside of a spherical cavity?

Click For Summary
Fluid entering a spherical cavity will create complex flow dynamics, potentially leading to turbulence and increased speed as it fills the space. If the cavity is closed, the air inside will compress, affecting the fluid behavior. Waves entering the cavity may reflect, possibly increasing their amplitude depending on the cavity's dimensions and fluid properties. The discussion emphasizes the need for a detailed scenario, including factors like the type of fluid, pressure conditions, and the source of the influx. A comprehensive problem description is essential for accurate analysis and predictions regarding fluid behavior in this context.

Suppose you have a spherical cavity, with a flow of a fluid ( in particular water), entering it from one side. What will happen to this flow? Will it create turbulences? Will speed increase? Will eventual waves entering the cavity be reflected, so creating waves with bigger amplitude?
Suppose the cavity is closed and doesn't allow water to exit .Only to enter.

What's inside the cavity ? If there's air it will be compressed while th cavern fills up. You'll have to tell us some more details for this scenario to work it out ...
 
Suppose it is on the surface of the sea, for example. So, the lower part is filled with water. The upper part is filled with air.
 
Why do you bring in the sea ? Try to paint a complete picture and set up a complete problem description. We're not telepathic.
Ideal fluid ? 'Infinite pressure' allowed ? What causes the influx ?

Topic about reference frames, center of rotation, postion of origin etc Comoving ref. frame is frame that is attached to moving object, does that mean, in that frame translation and rotation of object is zero, because origin and axes(x,y,z) are fixed to object? Is it same if you place origin of frame at object center of mass or at object tail? What type of comoving frame exist? What is lab frame? If we talk about center of rotation do we always need to specified from what frame we observe?
