PPT-Lesson 21 Laminar and Turbulent Flow

DESCRIBE the characteristics and flow velocity profiles of laminar flow and turbulent flow DEFINE the property of viscosity DESCRIBE how the viscosity of a fluid varies with temperature DESCRIBE . Laminar Turbulent Laminar flow Laminar flow is orderly follows known theory and is therefore predictable Accurate results can be achieved by numerical solution of the differential equations governing the fluid flow and heat transfer Turbulent 1 Friction factor for laminar 64258ow 5 1 Laminar or turbulent 64258ow The 64258ow of a 64258uid in a pipe may be laminar 64258ow or it may be turbule nt 64258ow Osborne Reynolds 18421912 a British scientist and mathematici Esco Airstream Laminar Flow Clean Bench Laminar Flow Clean Benches, Horizontal and Vertical (D-Series) 2 2 2 Airstream Horizontal Laminar Flow Clean Bench, Model AHC-4D_.Shown with optional caster wh CE30460 - Fluid Mechanics.

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. In laminar flow, the fluid moves smoothly in orderly layers, with little or no mixing of the fluid across the flow stream. . With laminar flow, there can still exist changes in velocity as the friction of the wall slows the layers closest to the wall, while the flow in the centre of the pipe moves at a faster pace. . : .
