So far our discussion of turbulence modeling has centered around separating the flow into resolved and . LAMINAR FLOW . V.S. TURBULENT FLOW. This shows turbulence because it’s all over the place and rough. This part of the picture shows Laminar Flow because it runs very smoothly. . Mark Rast. Laboratory for Atmospheric and Space Physics.
