Class
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);
