Detailed Description

Profile model where polar lift and drag coefficients are computed as sum of trigonometric series by using an input angle of attack.

\[ C_d = \sum_i\left(C_{dCoeff} \cos(i \alpha) \right) \]

\[ C_l = \sum_i\left(C_{lCoeff} \sin(i \alpha) \right) \]

where

\( C_d \) = Drag coefficient
\( C_l \) = Lift coefficient
\( \alpha \) = Angle of attack [deg]
Usage
Minimal example by using constant/fvOptions: rotorDiskSource1 { Mandatory/Optional (inherited) entries ...

Mandatory entries (runtime modifiable) profiles { Mandatory entries (runtime modifiable) <profile1> { Mandatory entries (runtime modifiable) type series; CdCoeffs (coeff1 coeff2 ... coeffN); ClCoeffs (coeff1 coeff2 ... coeffN); }

Mandatory/Optional (inherited) entries ... } }

where the entries mean:

Property Description Type Reqd Dflt
CdCoeffs List of drag coefficients scalarList yes -
ClCoeffs List of lift coefficients scalarList yes -
Note
  • Angle of attack is internally converted from [deg] to [rad].
