Bear in mind that in streamlining,we're dealing with pressure,not inertia and momentum.
Pressure converted to velocity by dislocation will seek equilibrium,flowing towards regions of lower pressure until de-dislocated,at which time it will return to pressure either by streamlining or viscous attrition.
