Fluid Mechanics: Dimensional Analysis: Buckingham Pi Theorem

Fluid Mechanics/Dimensional Analysis. Dimensional analysis is a mathematical technique used to predict physical parameters that influence the flow in fluid mechanics, heat transfer in thermodynamics, and so forth. The analysis involves the fundamental units of dimensions MLT: mass, length, and time. See more The defined units are based on the modern MLT system: mass, length, time. All other quantities can be expressed in terms of these basic units. For example,Force /area×veilocity gradient MLT^-2/L^2×T^-1 … See more Using the Buckingham π Theorem, we will now examine the π groups which appear most frequently in fluid dynamics. Most fluid flow situations depend on the following quantities: … See more An elementary method for finding a functional relationship with respect to a parameter in interest is the Rayleigh Method, and will be … See more This method will be illustrated by the same example as that for Rayleigh Method, the drag on a ship.
