Prandtl’s (“PRAHN-tull’s”) boundary layer theory describes shear forces arising in systems that approach this flow regime. For 10 points each:
[10h] Name this flow regime described by the Euler equations. This flow regime occurs when the term containing “del-squared v” in the Navier-Stokes equations vanishes.
ANSWER: inviscid flow [or zero-viscosity flow]
[10m] Flows that are near-inviscid necessarily have a high value for this quantity, which is equal to the product of characteristic length and flow velocity divided by kinematic viscosity.
ANSWER: Reynolds number
[10e] Because the Reynolds number is very large when approaching inviscid flow, low-viscosity regimes also exhibit this kind of chaotic, irregular flow.
ANSWER: turbulent flow [or turbulence]
