Chapter 2 Governing Equations of Fluid Dynamics

eng.auburn.edu

These integral forms of the governing equations can be manipulated to indirectly obtain partial differential equations. The equations so obtained from the finite control volume fixed in space (left side of Fig. 2.1a), in either integral or partial differential form, are called the conservation form of the governing equations.

How differential equations are derived? They are derived from the three fundamental laws of physics of which most engineering analyses involve. These laws are: (1) The law of conservation of mass, (2) The law of conservation of energy, and (3) The law of conservation of momentum.

THE DIFFERENTIAL EQUATIONS OF FLOW

www.columbia.edu

These equations are very useful when detailed information on a flow system is required, such as the velocity, temperature and concentration profiles. The differential equations of flow are derived by considering a differential volume element of fluid and describing mathematically a) the conservation of mass of fluid entering and leaving the control

The most elemental form of the Navier–Stokes equations is obtained when the conservation relation is applied to momentum. Writing momentum as gives: where is a dyad, a special case of tensor product, which results in a second rank tensor; the divergence of a second rank tensor is again a vector (a first rank tensor)[1]. Noting that a body ...
