Term Laminar flow Definition closely follows expanding outline, tends to separate as outline narrows Term Tapering trailing end flow Definition Tapering and trailing end into tear-drop shape reduces tendency for moving fluid to separate from body, further reducing drag. Term Crecent-shaped caudal fin flow Definition puts most find outside turbulent wake. tapering to points allows find to spill own turbulence as minimum vortices.
