WebAug 21, 2014 · Due to this, the viscous forces are assisted, causing the flow to reattach and get separated further downstream, resulting in a smaller wake in the process. The drag-crisis occurs at R e = 10 5 − 10 6 for a long-cylinder. After the drag-crisis, as Re is further increased, the separation begins to be drawn upstream again, causing an increase ... WebJun 24, 2024 · Flow past a cylinder and a sphere goes through a number of transitions with velocity as shown in this figure: In all of the cases presented on this figure, the density, viscosity, and diameter of the ball are the same. The flow velocity is gradually increased from the left to increase the Reynolds number. The drag for each case number is noted ...

In fluid mechanics, the Reynolds number (Re) is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between inertial and viscous forces. At low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow, while at high Reynolds numbers, flows … See more The Reynolds number is the ratio of inertial forces to viscous forces within a fluid that is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a See more For flow in a pipe or tube, the Reynolds number is generally defined as where • DH is the hydraulic diameter of the pipe (the inside diameter if the pipe is circular) (m), See more For a fluid moving between two plane parallel surfaces—where the width is much greater than the space between the plates—then the … See more Reynolds numbers are used in airfoil design to (among other things) manage "scale effect" when computing/comparing characteristics (a tiny wing, scaled to be huge, will perform … See more Osborne Reynolds famously studied the conditions in which the flow of fluid in pipes transitioned from laminar flow to turbulent flow. In his 1883 paper Reynolds described the … See more In boundary layer flow over a flat plate, experiments confirm that, after a certain length of flow, a laminar boundary layer will become unstable and turbulent. This instability occurs … See more For calculating the flow of liquid with a free surface, the hydraulic radius must be determined.
