Target entity: Kármán vortex street
Context triple: [Theodore von Kármán, knownFor, Kármán vortex street]
  • A. Langmuir circulation
    Langmuir circulation is a wind-driven pattern of shallow, counter-rotating vortices in the upper ocean that organizes floating material into parallel streaks on the water surface.
  • B. 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.
  • C. Saffman
    Saffman is a surname most notably associated with Philip G. Saffman, a prominent British-American applied mathematician and fluid dynamicist.
  • D. Ekman layer
    The Ekman layer is the thin region of fluid near a boundary (such as the ocean surface or seafloor) where the balance between friction and the Coriolis effect causes the flow to spiral with depth.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
