Pre-Analysis & Start-Up

Pre-Analysis

One simple hand-calculation that we can do now before even starting our simulation is to find theoretical wind velocity at the tip. We can then later compare our answer with what we get from our simulation to verify that they agree. 

The velocity, v, on the blade should follow the formula

\begin

Unknown macro: {equation*}

v=r \times \omega_{}
\end

 

Unknown macro: {latex}

\begin

Unknown macro: {equation*}

\mathbf{m \ddot

Unknown macro: {x}

+ k x =0}
\end

 

Unknown macro: {latex}

\begin

Unknown macro: {equation*}

m \ddot

Unknown macro: {x}

+ k x =0
\end

Plugging in our angular velocity of -2.22 rad/s and using the blade length of 43.2 meters plus 1 meter to account for the distance from the root to the hub, we get

\end

\begin
