02 continuity, streamlines and stream function Flashcards
1
Q
what do the navier-stokes equations describe?
A
describe how the velocity, pressure, temperature and density of a viscous moving fluid are related, encompassing momentum, mass continuity and energy
ie they describe the motion of viscous fluids
used in CFD
2
Q
the instantaneous velocity vector (V) can be found for any point along a 2D streamline, with which two components?
A
u and v
3
Q
when is the scalar stream function constant along a streamline?
A
always
4
Q
can flow move across streamlines?
A
no
5
Q
TRUE OR FALSE: the conservation equations can be applied to a stream tube as if it is isolated from the surrounding flow.
A
TRUE
