Fluids dimensional analysis
Did you know?
WebDimensional analysis is a very powerful tool, not just in fluid mechanics, but in many disciplines. It provides a way to plan and carry out experiments, and enables one to scale up results from model to prototype. Consider, for example, the design of an airplane wing. The full-size wing, or prototype, has some chord WebThe principles of dimensional analysis are developed from the principle of dimensional homogeneity which is self evident. It is characteristic of physical equations that only like quantities, that is those systems having the same dimensions, are added or equated. It is OK to to equate forces. ( 5 newtons = 2 newtons + 3 newtons.)
WebAdvantages of dimensional analysis 1) Reduce the number of variables: Suppose the force F on a particular body shape immersed in a stream of fluid depends only on the body length L, velocity V, fluid density é and viscosity ä: (L B :,, é, ä ; In general, it takes about 10 points to define a curve.
