At present it remains to address why the fast solar wind is and slow slow. Recently we have shown that field line curvature may substantially influence speed $v$, thereby offering an explanation for Arge et al. finding $v$ depends on more than just flow tube expansion factor. Here show by extensive numerical examples correlation between valid rather general base boundary conditions heating functions. Furthermore, effect of even pronounced when proton-alpha particle difference examined. We suggest any model has take into account shape quantitative analysis be made.
