back mixing meaning

• [Chemical engineering]
  "The tendency of reacted chemicals to intermingle with unreacted feed in reactors, such as stirred tanks, packed towers, and baffled tanks."

• Essentially no back mixing is assumed with " plugs " of fluid passing through the reactor.
• An ideal plug flow is assumed i . e . any flow velocities are constant and no back mixing of components happens.
• Cone came back mixing with his off-speed stuff with the inside fastball to strike out Mickey Tettleton to end the inning.
• For the case of catalytic gas-phase reaction process, gas back mixing should be avoided thus the reacted product is the gas phase.
• Though the circulating fluidized beds are used widely, the CFD, which can be, describe by non-uniformity flow patterns and a thorough back mixing still possess significant radial gradients in the particle density and a lower solid holdup inside the riser interior compared to the wall of the reactor.
