It’s not diffusion, but this process is assumed to be “perfect” in the derivation of the Scheil–Gulliver equation used in metallurgy. This process is facilitated by eddy generation in an “oscillatory baffled” device. The residence time distribution assumes a Dirac delta function in a model where this process does not occur axially. This process names a model of devices commonly contrasted with the plug-flow model and the batch model. A type of chemical reactor is named for this process occurring “continuously” within a “tank.” (10[1])Small devices made of alnico (10[1])and coated with Teflon are placed in a vessel above a plate in a simple method (10[1]-5[1])for this task. For 10 points, name this process often performed by magnetic “bars,” which aims (10[1])to homogenize (10[2])a solution’s components. ■END■ (10[2])
