How does a fluid behave inside of a spherical cavity?

Click For Summary
SUMMARY

The discussion focuses on the behavior of fluid dynamics within a spherical cavity, specifically when water enters from one side. It establishes that the flow can create turbulence and potentially increase speed, while also considering the effects of wave reflection within the cavity. The scenario assumes a closed cavity filled with air at the top and water at the bottom, emphasizing the need for a complete problem description to analyze the dynamics accurately. Key factors include the type of fluid, the presence of air, and the conditions under which the fluid enters the cavity.

PREREQUISITES
  • Fluid dynamics principles
  • Understanding of turbulence in fluid flow
  • Wave behavior in confined spaces
  • Basic concepts of pressure and fluid compression
NEXT STEPS
  • Research the Navier-Stokes equations for fluid flow analysis
  • Study the effects of turbulence on flow patterns in spherical geometries
  • Explore wave reflection and interference in confined fluid systems
  • Investigate the impact of pressure changes in closed fluid systems
USEFUL FOR

This discussion is beneficial for fluid dynamics researchers, engineers working on hydraulic systems, and students studying advanced fluid mechanics concepts.

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 ?
