| 1 | Investigation of grain mass flow in a mixed flow dryer显示文摘The numerical modeling of grain drying is a topic of great relevance to post-harvest engineering. The required type of drying process depends on the quantity of grain to be dried and the required quality of the grain. The choice of the drying system depends on the operating parameters of the drying process.The granular flow pattern of the material exerts a significant influence on the drying process. Post-harvest drying of grain is essential for better storage, handling, and processing. Therefore, it is important to know the material behavior that controls the particle flow patterns of grain in the drying equipment to guarantee the product quality and to optimize the drying process conditions. The discrete element method(DEM)was applied to investigate the particle flow pattern of wheat through a mixed-flow dryer(MFD) without airflow, and the findings were compared with experimental results in this work. The investigations were performed using dry wheat with 14 wb% moisture content. | Fabian Weigler Jochen Mellmann | 2014 | Particuology2014，12，1： | 14 |

| 4 | Influence of the number of flights on the dilute phase ratio in flighted rotating drums by PTV measurements and DEM simulations显示文摘Particle distribution in the cross-section of the flighted rotating drum(FRD)is critical to the analysis of heat and mass transfer between gas and solids.In this work,the particle tracking velocimetry(PTV)method is applied to study the influence of the number of flights on the particle motion in FRDs.The drum,installed with 1,4,8,or 12 rectangular flights,is filled with plastic balls to 15%and operated at various rotating speeds ranging from 10 rpm to 30 rpm.The results show that the number of flights has different effects on the holdup ratio and cascading rate of single flight and active flights.With 8 and 12 flights,the FRD produces a larger and more stable particle ratio of the dilute phase.Moreover,DEM simulations agree with PTV measurements,whereas literature models show significant deviations. | Lanyue Zhang Zhaochen Jiang Jochen Mellmann Fabian Weigler Fabian Herz Andreas Bück Evangelos Tsotsas | 2021 | Particuology2021，19，3： | 0 |
