dc.description.abstract | 本論文使用一個含有可以迅速開起的閘門之滑道和新穎的數位影像擷取裝置來觀察高濃度固液二相流之流場分析。該水槽含有一個放置空間來控制初始狀態,並且可輕易觀測流場的流動狀態。在流體側邊與表面的顆粒,可以用高速攝影機來拍攝其行為。並且用影像處理方法找出我們所需要的資訊。包含速度分布,固體密度等等。本論文將使用此方法探討摩擦力與顆粒流之間的關係。 | zh_TW |
dc.description.abstract | A laboratory-scale flume has been developed and integrated with a high-speed image acquisition system to investigate the unsteady bulk motion of a dry and a wet granular mixture. Monatomic Polyoxymethylene (POM) spheres and water are employed to prepare the experimental materials.
An image analysis routine has been developed to achieve efficient tracking for the individual particles within a moving bulk. Special efforts are made to examine how the coexisting liquid modifies the flow properties of a wet mixture from that exhibits by the dry bulk. The basal friction and the corresponding friction coefficients, that are typically difficult to measure, are estimated using image analysis and control volume analysis. | en |
