External Flows The subject of external flows involves both low Reynolds-number flows and high Reynolds-number flows. Low Reynolds-number flows are not of interest in most engineering applications and will not be considered; flow around spray droplets, river sediment, filaments, and red blood cells would be examples that are left to the specialists. High Reynolds-number flows, […]

7.1 Laminar Flow Between Rotating Cylinders Steady flow between concentric cylinders, as shown in Fig. 7.6, is another example of a laminar flow that we can solve analytically. Such a flow exists below a Reynolds number5 of 1700. Above 1700, the flow might be a complex laminar flow or a turbulent flow. We will again […]

6.1 Similitude After the dimensionless parameters have been identified and a study on a model has been accomplished in a laboratory, similitude allows us to predict the behavior of a prototype from the measurements made on the model. The measurements on the model of a ship in a towing basin or on the model of […]

Dimensional Analysis and Similitude Many problems of interest in fluid mechanics cannot be solved using the integral and/or differential equations. Wind motions around a football stadium, the air flow around the deflector on a semitruck, the wave motion around a pier or a ship, and air flow around aircraft are all examples of problems which […]
