| 2 | Vibration induced flow in hoppers:DEM 2D polygon model显示文摘A two-dimensional discrete element model (DEM) simulation of cohesive polygonal particles has been developed to assess the benefit of point source vibration to induce flow in wedge-shaped hoppers. The particle-particle interaction model used is based on a multi-contact principle. The first part of the study investigated particle discharge under gravity without vibration to determine the critical orifice size (Bc) to just sustain flow as a function of particle shape. It is shown that polygonal-shaped particles need a larger orifice than circular particles. It is also shown that Bc decreases as the number of particle vertices increases. Addition of circular particles promotes flow of polygons in a linear manner. The second part of the study showed that vibration could enhance flow, effectively reducing Bc. The model demonstrated the importance of vibrator location (height), consistent with previous continuum model results, and vibration amplitude in enhancing flow. | Feras Y. Fraige Paul A.

| 5 | Synchronization of Radar Observations with Multi-Scale Storm Tracking显示文摘The 3-D radar reflectivity data has become increasingly important for use in data assimilation towards convective scale numerical weather prediction as well as next generation precipitation estimation.Typically,reflectivity data from multiple radars are objectively analyzed and mosaiced onto a regional 3-D Cartesian grid prior to being assimilated into the models.One of the scientific issues associated with the mosaic of multi-radar observations is the synchronization of all the observations.Since radar data is usually rapidly updated(~every 5-10 min),it is common in current multi-radar mosaic techniques to combine multiple radar' observations within a time window by assuming that the storms are steady within the window.The assumption holds well for slow evolving precipitation systems,but for fast evolving convective storms,this assumption may be violated and the mosaic of radar observations at different times may result in inaccurate storm structure depictions.This study investigates the impact of synchronization on storm structures in multiple radar data analyses using a multi-scale storm tracking algorithm. | 杨洪平 Jian ZHANG Carrie LANGSTON | 2009 | Advances in Atmospheric Sciences2009，26，1： | 2 |
