On Mixing of Solids with Mixing Aid

Avalanche Mixing of Granular Solids

– Mixing of two fractions of a granular material in a slowly rotating two-dimensional drum is considered. The rotation is around the axis of the upright drum. The drum is filled partially, and mixing occurs only at a free surface of the material. We propose a simple theory of the mixing process which describes a real experiment surprisingly well. The dependence of the mixing time on the drum fi...

The effect of flow parameters on mixing degree of a three dimensional rhombus micromixer with obstacles in the middle of the mixing channel using oscillatory inlet velocities

The previous studies of authors on passive micromixers indicated that the micromixers dividing the flow to several layers, such as rhombus micromixers and micromixers with obstacles in the middle of the mixing channel, have higher mixing degree than other types. Also, using of oscillatory inlet velocities is an active method to enhance the mixing efficiency of micromixers. Therefore, in this st...

Effect of Merging Angle on Turbulent Mixing Layers

Mixing English in Persian Print Advertising Discourse

This article intended to illustrate a profile of the impact of English in magazine print advertising in Iran, examining the quantitative results obtained from discourse analysis. Three issues of Khanevadeh Sabz and two issues of Zendegi Ideal, female-oriented and best-seller magazines published in 2011, were collected and a total of 261 advertisements was analyzed qualitatively. Results showed ...

Mixing

In this tutorial, we introduce the notion of a Markov chain and explore how it can be used to sample from a large set of configurations. Our primary focus is determining how quickly a Markov chain “mixes,” or converges to its stationary distribution, as this is the key factor in the running time. We provide an overview of several techniques used to establish good bounds on the mixing time. The ...
