Fluids conservation of energy
WebNov 30, 2011 · The energy equation (Eq. 4.3) represents conservation of energy of a fluid element. • The left side represents the rate of change of internal energy of a fluid element. There is a time component and a spatial component because the fluid element under consideration is moving. Webmomentum, and conservation of energy. Validity is retained if is a vector, in which case the vector-vector product in the second term will be a dyad. Conservation of momentum The most elemental form of the Navier–Stokes equations is obtained when the conservation relation is applied to momentum. Writing momentum as gives:
