Talk:Laminar flow

message: I am under the impression that inviscid flow is non-laminar. I think the point about inviscid flow should be changed to a point about creeping motion (Stokes flow) which is the exact opposite of inviscid flow - viscous effects are much greater than inertial effects. Any thoughts? Easyl 15:05, 12 January 2007 (UTC)

message: This article says Laminar flow occurs when the Reynolds number is < 2040, but the Reynolds number article says Laminar flow occurs when Re < 2300. Which is correct?  — Preceding unsigned comment added by Bungeh (talk • contribs) 03:24, 18 September 2012 (UTC)
replies: text: The two are almost the same. Reynolds numbers shown on diagrams are usually shown on a logarithmic scale. The logarithm of 2040 is almost the same as the logarithm of 2300. Also, Reynolds number is used in numerous different applications - internal diameter of a pipe; distance along a pipe; chord of an airfoil; span of a wing etc.Dolphin (t) 22:44, 30 May 2015 (UTC)

message: I appreciate the diagrams; however, I wonder if you can please provide a picture of what a laminar jet of water looks like also?

message: This article would benefit from a history section to describe the chronological development of our understanding of laminar flow and the people responsible.  FreeFlow99 (talk) 12:12, 31 December 2012 (UTC)
thread_title:  Article lacks history section 

message: the article made it sound like laminar/turbulent flow depended only on velocity but according to this it also depends on viscocity:

replies: text: Whether the flow in a flow field will be laminar or turbulent can be anticipated with some reliability by taking account of the Reynolds number. The Reynolds number is based on a representative speed, a characteristic length and the kinematic viscosity of the fluid.  Alternatively, if the Reynolds number is based on the dynamic viscosity of the fluid, then the density of the fluid is also significant. Dolphin (t) 01:45, 30 May 2015 (UTC)
