Foam::seriesProfile
|
|
|
|
Description
|
|
Series-up based profile data - drag and lift coefficients computed as
|
|
sum of cosine series
|
|
|
|
Cd = sum_i(CdCoeff)*cos(i*AOA)
|
|
Cl = sum_i(ClCoeff)*sin(i*AOA)
|
|
|
|
where:
|
|
AOA = angle of attack [deg] converted to [rad] internally
|
|
Cd = drag coefficent
|
|
Cl = lift coefficent
|
|
|
|
Input in two (arbitrary length) lists:
|
|
|
|
CdCoeffs (coeff1 coeff2 ... coeffN);
|
|
ClCoeffs (coeff1 coeff2 ... coeffN);
