Fluids B1
Cards in this deck (9)
- 1StreamlineA curve whose tangent is everywhere parallel to the velocity vector
- 2TrajectoryThe path followed by a particle in the fluid
( dr/dt = v[r,t] can be used to find ) - 3EquipotentialA curve along which the velocity potential φ is constant
- 4Local incompressibility conditiondiv(v) = 0
- 5Do trajectories and streamlines coincide?Only in a steady flow
- 6What is a Poiseuille flow?A flow induced by a pressure gradient. Consider an incompressible and Newtonian flow with a constant pressure drop delta_p over a tube length L.
- 7Poiseuille's lawFor a Poiseuille flow:
delta_p = Ratio * Q
Where Ratio is proportional to R^(-4) - 8What is the Navier-Stokes equation?asa;lskejf
- 9What is a Couette flow?A flow induced between two surfaces due to the motion of one surface relative to the other. Again consider incompressible Newtonian flow.
