marenv::wake::ElementarySource Struct Reference

#include <WakeTypes.h>

Public Attributes

double pos [3]
 Source centroid, m, NED.
 
double flowDir [3]
 Unit direction of the relative flow at the source (along the wake axis), NED.
 
double area
 The panel's own area, m^2; the footprint is D = sqrt(4 area / pi).
 
double momentumDeficit
 M = drag / (0.5 rho |U|^2), m^2; the effective thrust coefficient is C_T,eff = M / area.
 
double solidity = 0.0
 Solidity Sn of a porous panel, for nets the calculated solidity Snc (R56); Sn > 0 selects the MF2022 Eq. 11 near wake of ElementaryDeficit(), 0 keeps the pinned momentum-theory near wake.
 

Detailed Description

One elementary wake source, typically one net panel.

All positions and directions are in world NED at the build time t0; the builder transforms them into the frame of the field.
