acceleration); this term can be nonzero even for steady flows. It accounts
for the effect of the fluid particle moving (advecting or convecting) to a
new location in the flow, where the velocity field is different. For example,
nunan A Çengel | John M. Cinbala
consider steady flow of water through a garden hose nozzle (Fig. 4-8). We
define steady in the Eulerian frame of reference to be when properties at
any point in the flow field do not change with respect to time. Since the
velocity at the exit of the nozzle is larger than that at the nozzle entrance,
fluid particles clearly accelerate, even though the flow is steady. The accel-
eration is nonzero because of the advective acceleration terms in Eq. 4-9.
