Buckingham equation

Evaluating this integral and writing the result in terms of the flow characteristic gives the well-known Buckingham equation ... 

The Buckingham equation for Bingham flow in the laminar region is... 

Let us now review the group of papers discussing the relative weights of the different components in Buckingham equation (Equation (2.23)). Reaction field methods describe only long-range electrostatic interaction, the crE term (or, as in IEF-PCM, some of the (rw term [29]). In order to go beyond the continuum model some solvent molecules... 

Equation 3-61 is called the Buckingham equation. This equation cannot be solved without long iterations. Many engineers prefer to simplify the Buckingham equation by ignoring the term (tq/tJ, as this term is of negligible magnitude compared with the other terms ... 

In Chapter 3, in the description of the capillary tube test, the Buckingham equation was derived. When ignoring the fourth-power term, the equation reduces to... 

Bingham slurries. In some respects, it is a useful tool for hand calculations. A more widely accepted method since the mid 1980s is to compute the transition velocity that was proposed by Wilson and Thomas, to be discussed in Section 5-4-3. It is then assumed that the transition from laminar to turbulent flow occurs when the Wilson-Thomas and the Buckingham equations intersect. 

For the laminar flow regime fanning friction factor, Heywood (1991) modified the Buckingham equation to... 

Other force fields offer slight variations of either the Lennard-Jones or Buckingham equation. For example the latest force field in INSIGHT/DISCOVER [4] introduces a 9-6 rather than a 12-6 potential.
