Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley ... For instance, the distinction between an ...

We shall find that exactly the same problems arise again in fluids especially with very slow flows where the acceleration can be neglected and viscosity is dominant (so-called Stokes flow). Complete ...

The thermodynamic pressure is an absolute pressure which is calculated, for example, using the ideal gas equation of state. In contrast, flow is driven by the pressure difference between two locations ...

In addition to the treatment of the basic equations for modeling laminar, transient flow of viscous, incompressible fluids - the Navier-Stokes equations - the authors look at the simulation of free ...
