A new type of pin to be installed in the mixing section of a screw extruder is proposed based on the results of numerical calculation of flow field and local and integral mixing efficiency in the cross-section of a pin mixing section.
The influence on heat transfer of free sections between mixing sections has been studied.
A SAR mixer was constructed by aligning a series of thin plates to achieve six mixing sections.
In this study, the effects of the main operating parameters on system performance were experimentally investigated using R-11 as the working fluid and keeping constant the position of the primary nozzle end at the inlet plane of the mixing chamber section of the ejector.
The calculated results of local mixing efficiency indicate the location of regions of good or poor mixing in the cross-section of the mixing section, and the integral mixing efficiency provides the means to compare the mixing performance of different mixing sections.
This corresponds to a setting such that, exactly at the entrance of the mixing section — where the two flows start to interact —, the static pressures of the two mixing streams are equal.
Mixing enlarged technical drawings of engine parts, cut-away sections of pistons and engine blocks, coloured spirals, discs, targets and calibrated dashboard dials and temperature gauges, these vividly coloured tempera paintings might have been made today and are filled with optimism for a technological future.
The mixing region in the downstream section of the H-shaped channel is much smaller than that in the downstream section of a comparable rectangular channel.
Therefore, based on numerical simulations, the mixing characteristic of a T-shaped micro-reactor with rectangular cross sections is studied for three different flow regimes.
Mixing time number is a convenient parameter to characterize mixing performance of stirred tanks.
