Questions about the Fluid simulation systems in blender. Blender has two systems for simulating liquids, a SPH (Smoothed Particle Dynamics) system integrated with the particle system, and a Lattice Boltzmann method which can be used create a variety of simulations.

Can we make our fluid domain object from a cylinder?
Yes, you can use Cylinder object as domain, but shape is not used in calculation, only dimension of the object (see Xylvier's answer).
So just an extension ... if you need liquid inside cylindrical …

Set Flow object to XY dimension of Domain at a bottom so there are not a gaps between Domain boundary and Flow. Like the liquid (Flow) is in a rest shape.
Note: Previously I thought, liquid explosion …

blender (2.92 BETA) liquid simulation with viscosity becoming really stretched on one side
Because you are too close to a Domain border and since you have set collide with all sides of domain it probably stick to it.
When I move it at center it seems to be fine.
Consider if Domain dimensio …

Your issue is Liquid > Diffusion setup ... I'm not a math guy, but from presets it looks like Base shouldn't be bigger than Exponent. If you disable Diffusion feature or if you use some of the given p …

Gravity is relative and not absolute?
Yes ... transforming domain's rotation calculates sim gravity in Local Z axis. Hard to say if it is for result stability (avoid some issues or glitches) or missing feature. Anyway you can set gravity …

Is there a way to hide/remove parts of a fluid sim mesh so they won't show in render?
