equation-fit model uses non-dimensional equations developed from curve-fits to manufacturer’s performance data. These curve fits are used to predict the condenser performance in cooling (and heating) mode. Least squares regression is used to generate a set of performance coefficients ... The governing equations for the cooling performance are ...

The governing equations for the velocity and pressure fields are partial differential equations that are applicable at every point in a fluid that is being modeled as a continuum. When they are integrated in any given situation, we can expect to see arbitrary functions or …

The governing equations can also be obtained by direct application of Lagrange’s Equation. This approach is quite straightforward. The expression for kinetic energy is 2 1 T = m i x˙2; (12) 2 n=1 the expression for the potential is V = 1/2k 1x 2 +1/2k 2(x 2 − x 1)2 +1/2k 3x 2 (13) 1 Applying Lagrange’s equation to T − V = L d dt ∂L

Derivation of the Navier-Stokes Equations

web.cse.ohio-state.edu

VII. Derivation of the Navier-Stokes Equations and Solutions In this chapter, we will derive the equations governing 2-D, unsteady, compressible viscous flows. These equations (and their 3-D form) are called the Navier-Stokes equations. They were developed by Navier in 1831, and more rigorously be Stokes in 1845.
