Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Strouhal number | Statement: [Kármán vortex street, describedBy, Strouhal number]

Target entity: Strouhal number
Context triple: [Kármán vortex street, describedBy, Strouhal number]

• A. Stokes number
  The Stokes number is a dimensionless quantity in fluid dynamics that characterizes the behavior of particles suspended in a flow by comparing their response time to a characteristic timescale of the fluid.
• B. Reynolds number
  The Reynolds number is a dimensionless quantity in fluid mechanics that characterizes the flow regime of a fluid, indicating whether it is laminar or turbulent based on the ratio of inertial to viscous forces.
• C. Froude number
  The Froude number is a dimensionless quantity in fluid dynamics that compares inertial forces to gravitational forces, commonly used to characterize flow regimes in open channels and around ships.
• D. Kármán vortex street
  Kármán vortex street is a repeating pattern of swirling vortices formed when a fluid flows past a bluff body, fundamental in fluid dynamics and aerodynamics.
• E. Brunt–Väisälä frequency
  The Brunt–Väisälä frequency is a measure of the stability of a stratified fluid to vertical displacements, representing the natural oscillation frequency of buoyancy-driven gravity waves in atmospheres, oceans, and stellar interiors.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
