| dc.description.abstract | 顆粒氣體的聚集現象源自於顆粒間的非彈性碰撞，二元顆粒氣體在二格容器中的行為與組成顆粒的種類、數量及輸入能量有關。本文首先以不同顆粒材質、粒徑與輸入能量為實驗變因，分析以上因素對於顆粒聚集數量的影響。接著在單顆不同材質的大顆粒混入後觀察小顆粒聚集數量變化，並於固定輸入能量下觀察顆粒系統運動狀態與大、小顆粒數量的關係。最後，透過水平分離指數的建立利用已知的顆粒組合，針對數量配比、材質的變化分析水平分離現象的特性，以期達到工業上顆粒純化方面的應用。 | zh_TW |
| dc.description.abstract | Clustering phenomenon of granular gas results from inelastic collision between particles. The collision behavior of two-compartmentalized bi-dispersed granular gas depends on the material property and number of particles as well as input energy. In this thesis, we investigate numbers of mono-dispersed particle clustering with different materials, particle size and input energy. Furthermore, small particle clustering mixed with one large particle composed of different materials and the motion state of bi-dispersed granular gas with different number of small/large particles are studied. Finally, by determining index of horizontal segregation, the properties of horizontal segregation are investigated with several parameters, such as the number of small/large particles and different material properties. We expect to extend our experimental results to the industrial application of particle purification. | en |
