WebSep 12, 2024 · In turbulent flow, the paths of the fluid flow are irregular as different parts of the fluid mix together or form small circular regions that resemble whirlpools. This can occur when the speed of the fluid reaches a certain critical speed. Figure 14.7.2: (a) Laminar flow can be thought of as layers of fluid moving in parallel, regular paths. WebThe flow of a fluid can be represented by Streamlines, which are ‘fluid elements’ that move relative to each other. In Laminar Flow, all the fluid elements flow in the same direction, and none of the streamlines cross over. It usually occurs at lower velocities and with streamlined objects. orange flowering perennials

The pattern depends on a dimensionless scale number, determined by sphere radius, frequency of oscillation, and kinematic viscosity of the fluid.

WebDec 21, 2015 · In turbulent flow the friction is inertial for the most part: the chaotic flow causes the fluid in the faster moving center to interchange randomly with the fluid near the edge. This eventually allows momentum from the center to be transferred to the walls of the pipe (i.e. friction).
