Hi, guys, i tried to read the definitions of laminar and turbulent flowon some of the website, but had difficult time understanding them. I am wondering if you guys can explain the above terms in more plain words?
Laminar flow is a smooth, orderly flow of a fluid in a straight path, while turbulent flow is a chaotic, irregular flow with fluctuations and eddies.
Laminar flow is caused by low fluid velocity and high fluid viscosity, while turbulent flow is caused by high fluid velocity and low fluid viscosity.
Yes, when the fluid velocity increases, laminar flow can transition into turbulent flow due to the onset of instabilities and fluctuations.
The Reynolds number is used to determine the type of flow. A Reynolds number below 2000 indicates laminar flow, while a Reynolds number above 4000 indicates turbulent flow.
Laminar flow is more efficient for heat and mass transfer as it creates a thin boundary layer between the fluid and the surface, allowing for better transfer of heat and mass.
