Dimensional 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.

Dimensional Analysis вЂў Consider that we are interested in determining how the drag force acting on a smooth sphere immersed in a uniform flow depends on other fluid and flow Non-dimensional groups in fluid mechanics References White (2011) вЂ“ Chapter 5 Hamill (2011) вЂ“ Chapter 10 Chadwick and Morfett (2013) вЂ“ Chapter 11 Massey (2011) вЂ“ Chapter 5 . Hydraulics 2 T3-2 David Apsley 1. WHAT IS DIMENSIONAL ANALYSIS? Dimensional analysis is a means of simplifying a physical problem by appealing to dimensional homogeneity to reduce the number of вЂ¦ TsienвЂ™s observation on the importance of dimensional analysis in Explosion Mechanics and in other п¬Ѓelds. вЂвЂProblems in the п¬Ѓeld of Explosion Mechanics are much more complicated than problems of classical Solid Mechanics or Fluid Mechanics, so it does not seem suitable to start with fundamental principles of mechanics in order to con- struct theoretical models for Explosion Mechanics Therefore, dimensional analysis tells us that drag coefficient is a universal function of the Reynolds number, regardless of the choice of fluid, sphere diameter or the settling velocity.
