“…In order to optimize the mixer, investigations of apical angle and groups of the triangles have also been done using simulations, as is shown in Fig. . The mixing effect was improved with the growth of the apical angle of the triangle baffles from 30 to 150°.…”

Micromixing plays a significant role in microfluidics. Here a passive mixer with triangle baffles embedded in the main channel was designed, fabricated and characterized. Systematic simulations and experiments have been done with the increase of Reynolds number (Re), ranging from 0.1 to 500. All results confirmed the improvement of mixing within a short distance (<6.4 mm). At common flow rate of microfluidics (Re = 1.0), 'the percentage of mixing' (φ) can be 85.5% by the distance of 6.4 mm, which is 2.48-fold better than that of common Y-mixer. φ values of the design containing triangle baffles are 4.75-time at Re of 100 and 8.32-time at Re of 500 better than those of the common Y-mixer at the distance of 6.4 mm, respectively. The mixing effect caused by different apical angle and the number of triangles was also investigated using simulations. The mixing effect was improved with the growth of the apical angle of the triangles from 30 to 150°. Similarly, more triangle baffles lead to better mixing effect.

It is well known that helical ribbon (HR) impellers exhibit poor bottom pumping properties. Three different HR impeller geometries, varying in their bottom design, are compared in terms of their mixing performance. Particular emphasis is given to the improvement of pumping capabilities. The selected bottom geometries were a standard bottom termination, an anchor-type termination and a paddle-type termination. The investigation was based on the use of 3D finite-element simulation to assess the hydrodynamics and mixing performance using various distributive and dispersive criteria. Analysis of Poincaré maps showed that an HR with a paddle-type termination operating in a down-pumping mode offered the best performance. 

Jet mixing when heating oil and fuel oil in storage tanks

This paper presents the research results of jet mixing and heating processes of crude oil of the Zachebashskoe field (Republic of Tatarstan) and fuel oil M100 in a tank with a capacity of 2000 m 3 . Circulation systems with nozzle inclination in the range from -25° up to 125° are considered. The presence and washing out of bottom sediments in the tank are modeled. The time required for removing the bottom sediments and for heating the tank to the optimum temperature is determined. The best heating for the tank with oil and fuel oil was observed at the nozzle inclination in the range from -25° up to 60°. The optimal nozzle inclination was 115° for washing out the bottom sediments in the oil tank. To remove sediment in a tank with fuel oil it is recommended to use the same nozzle inclinations as for heating.
