2. Laminar–turbulent transition - Wikipedia

   en.wikipedia.org/wiki/Laminar–turbulent_transition

   The path from receptivity to laminar-turbulent transition as illustrated by Morkovin, 1994 [2] A boundary layer can transition to turbulence through a number of paths. Which path is realized physically depends on the initial conditions such as initial disturbance amplitude and surface roughness.

3. Hemodynamics - Wikipedia

   A Reynolds number of less than 2300 is laminar fluid flow, which is characterized by constant flow motion, whereas a value of over 4000, is represented as turbulent flow. [16] Due to its smaller radius and lowest velocity compared to other vessels, the Reynolds number at the capillaries is very low, resulting in laminar instead of turbulent flow.

4. Gamma-Re Transition Model - Wikipedia

   en.wikipedia.org/wiki/Gamma-Re_Transition_Model

   Gamma-Re (γ-Re) transition model is a two equation model used in Computational Fluid Dynamics (CFD) to modify turbulent transport equations to simulate laminar, laminar-to-turbulent and turbulence states in a fluid flow. The Gamma-Re model does not intend to model the physics of the problem but attempts to fit a wide range of experiments and ...

5. Laminar flow - Wikipedia

   en.wikipedia.org/wiki/Laminar_flow

   A laminar flow reactor (LFR) is a reactor that uses laminar flow to study chemical reactions and process mechanisms. A laminar flow design for animal husbandry of rats for disease management was developed by Beall et al. 1971 and became a standard around the world [9] including in the then-Eastern Bloc. [10]

6. Reynolds number - Wikipedia

   en.wikipedia.org/wiki/Reynolds_number

   With respect to laminar and turbulent flow regimes: laminar flow occurs at low Reynolds numbers, where viscous forces are dominant, and is characterized by smooth, constant fluid motion; turbulent flow occurs at high Reynolds numbers and is dominated by inertial forces, which tend to produce chaotic eddies, vortices and other flow instabilities ...

7. Eddy (fluid dynamics) - Wikipedia

   en.wikipedia.org/wiki/Eddy_(fluid_dynamics)

   Turbulent flow is defined as the flow in which the system's inertial forces are dominant over the viscous forces. This phenomenon is described by Reynolds number, a unit-less number used to determine when turbulent flow will occur. Conceptually, the Reynolds number is the ratio between inertial forces and viscous forces.
