Behaviour of Fluids under strong gravitational field We were being given intro  to fluid dynamics at our school
So the thing that sparked me up is $ g$ in expression of:
Static pressure of fluid
Bernoulli Principle
I am curious how fluids(especially liquids) will behave when they are near or at strong gravitational fields and when they approach
near-implies--> You may not be on the body but  within distance $\epsilon$ such that $g$ of the body is not quite appreciably different from the maximum acceleration  due to gravity of body.
approach-implies--> AT some distance such that $g$ is increasing gradually or at some certain rate/
I suspect as the liquid approaches it may turning rigid.Something like the rate at which it turn rigid or loses it properties of fluid/liquid.This rate may affect quite of its properties(sorry i don't mathematical background or graduate physics background..I can only speculate as high school studentt)
But the things is this may be only the case for uber-strong gravitational fields such as those of blackholes
But what about massive structure?(think of stars having millions times mass than sun..exaggertaion?) which may not have $g$ like black holes but they are appreciably strong?
Since the strong gravitational field brings appreciable compressability therefore things like Bernouili might not be applicable
What incites me more is whether fluid(mainly liquids) will have different demeanour with boundary(as in contained in some container) and without boundary 
Will the geometery of boundary affect fluid?
I know this situation will be titled as illegal use of artistic licences at PhysSE but who know what potential-eenrgy black magic may craft dark things  out there in wild universe out there.  
Envision a situation that  $g$ is changing with respect to time and periodic then how liquid might behave(think of a massive body passing near fluid for certain period of time after a certain interval)
These are some of things that buggs me for now
Can somebody enlighten us  on this?
 A: A lot of work has been done in relativistic hydrodynamics and fluid dynamics, as well as relativistic kinetic theory. Both for special and general relativity. A couple reviews are below, and you'd get a general idea, but it's not straightforward.
Relativistic fluids are used to model matter and radiation in dense and collapsing stars (neutron stars, black holes collapsing), and that includes then how they behave in a gravitational field which they also create. So it is a very nonlinear problem. It is also used for instance to model cosmology, the matter and radiation density, pressure and shear/stress of the matter and radiation in the universe, in large scale. From that we know for instance how the cosmological expansion of the universe affects the matter and radiation densities over time.
In strong gravity, i.e. General Relativity, it is not easy to solve for any complicated fluid models, so usually one picks equations of state (density as function of pressure and temperature for instance, in the fluid, dependent on what kind of fluid it is) to model,it, and can get some analytical and if not numerical solutions. One of the earliest models of collapse is the TOV equation (you can google it) for collapse, where they assumed a pressureless fluid. For effects like turbulence it is hard to obtain analytical solutions, and so they tend to be numerical ones or small perturbations off a base solution.
