The objective of this experiment is to demonstrate the differences between laminar, turbulent, and transitional fluid flow, and to determine the conditions under which these types of flow occurs.
The Reynolds number (Re) is a dimensionless number that give a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditi-
ons. Reynolds numbers frequently arise when performing dimensional anays-
is of fluid dynamics problems, and as such can be used to determine dyna-
mic similitude between different experimental cases. They are also used to characterize different flow regimes, such as laminar or turbulent flow : laiminar 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.
