Circulation Theory - Coggle Diagram
Circulation Theory
Flow around rotating cylinder
Where velocity is higher
Lower pressure
Magnus Effect
Betz
Smallest energy loss
Induced velocity
when helicoidal vortex sheet
pushed astern along shaft axis
rotated about shaft axis
Maximum efficiency
inflow velocity
same for every blade
Force acting on the cylinder
Kutta-Joukowski Equation
\( L=\rho \Gamma V_0 \)
\( \Gamma \)
strength of circulation flow
\(2 \pi c \)
\( V_0 \)
Uniform flow velocity
no need to consider
blade shape
Creation of vortices
at the edges
Free tip vortices
