The above discussion is restricted to incompressible flows. If the velocity of the object is sufficiently large, compressibility effects become important and the drag coefficient becomes a function of the Mach number, where c is the speed of sound in the fluid. The introduction of Mach number ...
The purpose of CFD is to map and quantify fluid flows in space and time. CFD simulations achieve this by solving the equations that govern flow: conservation of mass; balance of momentum; and conservation of energy. This chapter describes what these equations conceptually mean and how they are...
The fundamentals of fluid sealing, including seal operating regimes, are discussed and the general fluid-flow equations for fluid sealing are developed. Seal performance parameters such as leakage and power loss are presented. Included in the discussion are the effects of geometry, surface deformations...
10–6.10–3Our first approximation is the class of fluid flow called creeping flow.Other names for this class of flow include Stokes flow and low Reynoldsnumber flow. As the latter name implies, these are flows in which theReynolds number is very small (Re 1). By inspection of the ...
Suitable for a first course in fluid mechanics, this text presents the classical principles supported by numerous analyses of fluid flow phenomena. New sections have been added, such as turbomachines, an introduction to various ideas associated with computational fluid mechanics, two dimensional compressi...

This week: circuit diagrams, the written language of fluid power, and how fluid flows through conduits. We hope that you find the hydraulic circuits on the mowing machine as interesting as we did. WEEK 3 Components and Concepts: Part 2 This will be a busy week diving into valves and pum...
