Can switching muzzle brakes change muzzle velocity??

[QUOTE="adrexco, post: 1231248, member: 88101"] from a point of view of fluid dynamics, a brake must have an effect on the projectile velocity, The supersonic fluid column accompanying the projectile has to extend past the end of the barrel. A portion of the recoil energy is the thrust created from the exiting fluid column. Otherwise a brake would have no effect. Redirecting the laminar fluid column flow to a significantly different vector (like close to 90 deg) must have an effect on the projectile velocity. The more efficient the brake is on redirecting the fluid column thrust (reducing recoil), the less of the fluid column energy is available to assist the projectile against the static friction of atmosphere. I haven't really thought about this before, but I think there is more going on in the first foot or so of external ballistics then I've considered in the past. A very interesting thread! [/QUOTE]
