| 1 | Comparative analysis of different static mixers performance by CFD technique:An innovative mixer显示文摘The flow and mixing behavior of two miscible liquids has been studied in an innovative static mixer by using CFD,with Reynolds numbers ranging from 20 to 160.The performance of the new mixer is compared with those of Kenics,SMX,and Komax static mixers.The pressure drop ratio(Z-factor),coefficient of variation(CoV),and extensional efficiency(α)features have been used to evaluate power consumption,distributive mixing,and dispersive mixing performances,respectively,in all mixers.The model is firstly validated based on experimental data measured for the pressure drop ratio and the coefficient of variation.CFD results are consistent with measured data and those obtained by available correlations in the literature.The new mixer shows a superior mixing performance compared to the other mixers. | M.M.Haddadi S.H.Hosseini D.Rashtchian Martin Olazar | 2020 | Chinese Journal of Chemical Engineering2020，28，3： | 9 |
| 2 | Elutriation, attrition and segregation in a conical spouted bed with a fountain confiner显示文摘This study examined elutriation,attrition,and segregation in a conical spouted bed with a fountain confiner and incorporating an open sided draft tube.Fine silica sand with a wide particle size distribution was employed as a model material,operating in both the batch and continuous modes.The use of a fountain confiner is crucial when operating with fine particles,because otherwise the bed rapidly exhibits significant entrainment.The extent of attrition was quantified using a tracing technique based on differently-coloured sand fractions as well as monitoring size distributions by sieving.Particle breakage was found to be the primary attrition mechanism,and the fountain confiner was determined to limit the elutriation of fine particles resulting from breakage.Consequently,only a small fraction of the finest particles were entrained from the bed.The incorporation of a confiner increased operational stability while reducing segregation,especially in the upper half of the bed where the majority of segregation typically occurs.Thus,the bed was perfectly mixed apart from very minimal segregation close to the wall and at the bottom of the contactor.These results provide a basis for the design and operation of larger scale equipment for the continuous drying of materials. | Aitor Pablos Roberto Aguado Jorge Vicente Mikel Tellabide Javier Bilbao Martin Olazar | 2020 | Particuology2020，18，4： | 2 |
| 3 | Sand attrition in conical spouted beds显示文摘A study was carried out on the attrition in conical spouted beds using two sands with different properties for several bed heights and gas flow rates. Furthermore, the influence of a draft tube was studied at ambient and high temperatures. The main objective was to acquire knowledge on the attrition of sand beds for biomass pyrolysis in a pilot plant provided with a conical spouted bed reactor. A first-order kinetic equation is proposed for sand attrition in a conical spouted bed at room temperature. The predicted attrition rate constant depends exponentially on excess air velocity over that for minimum spouting. Both the draft tube and temperature increase contribute to reduction of attrition. | Aranzazu R.
