Hydrodynamics: Flow Characters

Question 1

Laminar

Answer 1

Streamlined, recttilinear, unstable

Question 2

Turbulent

Answer 2

non-linear, circular, stable

Question 3

Re

Answer 3

length*velocity/Kinematic constant
Ratio of inertial factors to viscous factors

Question 4

High Re

Answer 4

Turbulent flow, inertial forces dominate

Question 5

Low Re

Answer 5

Laminar flow, viscous forces dominate

Question 6

Shift from laminar to turbulent

Answer 6

Occurs around ~3000 Re

Question 7

Boundary layer

Answer 7

layer of reduced velocity that is immediatly adjacent to surface of an object
Reduces speed of organism, increase drag

Question 8

Transition Point

Answer 8

Occurs at ~1/3 max body depth

Question 9

Seperation point

Answer 9

where fluid at body surface begins to move forward
