【摘要】 以离心式渣浆泵叶轮和蜗室内的颗粒速度场分析为例,将高速摄影所得到的原始流动图象,经计算机接口转换为数字图象,应用VisualC++编制WINDOWS应用软件对这些图象进行处理,通过对不同位置颗粒的位移和相邻图象间所采样的时间计算出颗粒速度场。更多还原

【Abstract】 Analysis to speed field of particle in impeller and worm room of centrifugal slurry pump serves as example, initial flowing image obtained by high speed photography is transferred to digital image by computer interface. In order to deal with digital image, a Windows application software is programmed by Visual C++, and particle speed field is calculated by displacement of different particle and duration between two samplings.更多还原
