The position of the Source icon in the scene does not matter. If you have many Simulators in the scene, by default each Simulator will interact with a Source's Emitter Nodes as long as they are inside this Simulator. You can exclude Sources or Emitters from a Simulator's Scene Interaction rollout. If you use Include mode, you have to pick both the Source and its Emitter Nodes in the  Interaction List.

The Source can emit in 3 different Emit Modes - Surface Force mode creates fluid only at the surface of emitters, Volume Brush fills the entire volume of the emitters, and Volume Inject also fills the emitter's volume and adds pressure for an explosive effect.

The following video provides examples of Inherited Texture UVW coordinates repeating along the V-axis over 0, 1 and 2 seconds. When Variation is set to 0, the V coordinate remains static. If Variation is set to 1, it takes one second for a full repetition/tile along the V-axis.

Time Base | timebase – This parameter is used when emitting from particle systems. It allows you to animate the parameters using the age of the particle instead of the timeline frame time.
