20100142314 | Particle Interactions in a Fluid Flow - Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species.

20120106290 | STATIC MIXER COMPRISING A STATIC MIXING ELEMENT, METHOD OF MIXING A FLUID IN A CONDUIT AND A FORMULA FOR DESIGNING SUCH A STATIC MIXING ELEMENT - Using the Mapping Method different designs of SMX motionless mixers are analyzed and optimized. The three design parameters that constitute a specific SMX design are: the number of cross-bars over the width of channel, Nx, the number of parallel cross-bars per element, Np, and the angle between opposite cross-bars θ. Optimizing Nx, somewhat surprisingly reveals that in the standard design with Np=3, Nx=6 is the optimum using both energy efficiency as well as compactness as criteria. Increasing Nx results in under-stretching and decreasing Nx leads to over-stretching of the interface. Increasing Np makes interfacial stretching more effective by co-operating vortices. Comparing realized to optimal stretching, we find the optimum series for all possible SMX(n) designs to obey the universal design rule Np=(⅔)Nx−1, for Nx=3, 6, 9, 12, . . . | 05-03-2012 |
