A regression model for simulating residence time distribution (RTD) of turbulent flows in helical static mixers is proposed and developed to predict the residence time distribution in static mixers. An efficient method is required to estimate the RTD and the sole means of achieving this is through detailed regression model. The RTD was calculated numerically by regression model. The results of ...

Highly effective mixing in microchannels is important for most chemical reactions conducted in microfluidic chips. To obtain a rigid and chemically resistant micromixer system at low cost, we fabricated a Y-shaped microchannel with built-in mixer structures by static liquid photolithography (SLP) from methacrylated polyvinylsilazane (MPVSZ) as an inorganic polymer photoresist which was then con...

A compact static mixer for gas–liquid dispersion in pipelines is studied this paper with a Reynolds averaged two fluid model approach. procedure based on the lumped parameter solution of population balance applied to obtain bubble Sauter mean diameter needed interphase forces. The gas distribution pipe analyzed different operative conditions and efficiency assessed terms homogeneity section, lo...

The numerical model of the granular flow within an aggregate mixture, conducted in vertical static and/or conveyor blender, was explored using discrete element method (DEM) approach. blending quality limestone fine fractions binary mixture for application self-compacting concrete studied. potential augmenting mixer working efficiency by joining its operation to a Komax-type mixer, increase cond...
