How this entity was disambiguated
This entity first appeared as the object of triple T7051672 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Taylor–Couette flow Context triple: [G. I. Taylor, knownFor, Taylor–Couette flow]
-
A.
Rayleigh–Bénard convection
Rayleigh–Bénard convection is a fluid dynamics phenomenon in which a horizontal fluid layer heated from below develops organized convection cells due to buoyancy-driven instability.
-
B.
Stokes flow
Stokes flow is a type of fluid motion dominated by viscous forces and characterized by very low Reynolds numbers, where inertial effects are negligible.
-
C.
Callahan flow
Callahan flow is a notable basaltic lava flow associated with Medicine Lake Volcano in northern California, formed during one of its relatively recent volcanic eruptions.
-
D.
Saffman–Taylor instability
The Saffman–Taylor instability is a fluid dynamics phenomenon in which a less viscous fluid penetrating a more viscous one in a confined geometry leads to finger-like interfacial patterns, often called viscous fingering.
-
E.
Turbulent Flows
Turbulent Flows is a comprehensive graduate-level textbook that rigorously presents the theory, modeling, and simulation of turbulent fluid motion in engineering and physics.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
