| 英文摘要 | We consider the micromixing enhancement by pulsating flows. dimensionless governing equations and boundary conditions were developed for t-type micromixers with two inlet pulsating flows. the problem involves a set of parameters. three key dimensionless parameters are identified: the reynolds number, the strouhal number, and the disturbance amplitude. suitable strouhal number or disturbance amplitude causes symmetrical meniscus-shape mixing interfaces, separating the whole mixing channel into a set of segments. thus uniform exit species concentration can be reached. too large or too small strouhal number or disturbance amplitude yields the meniscus-shape mixing interfaces deviating from the centerline of the mixing channel, deteriorating the mixing performance. the optimized disturbance amplitude is increased with increases in strouhal numbers. low reynolds number needs larger disturbance amplitude.
