Developing a shear thinning non-Newtonian fluid to substitute blood is desirable in studies of biomedicine engineering since blood is a shearing thinning non-Newtonian fluid that exhibits both viscous and elastic properties,and generally not available in large volume.
运用美国brook公司生产的PVS Rheometer型旋流变仪对黄原胶溶液流变特性实验发现,黄原胶溶液是一种典型的剪切稀化流体,其剪切应力和剪切速率符合幂律分布;黄原胶溶液浓度越高,其剪切稀化特性越强;黄原胶溶液的表观粘度与溶液温度成反比,与溶液浓度成正比;人体血液的表观粘度介于0。
The effect of clearance of bearing and shear thinning on lubricant characteristic was analyzed synthetically under thin film lubrication.
综合考虑薄膜润滑条件下间隙变化和剪切稀化对润滑剂性能的双重影响,得到了润滑剂在剪切稀化下的等效粘度模型,由此推导出考虑剪切稀化时的广义Reynolds方程和能量方程,得到了温度场的分布规律和温度与各性能参数的关系。
According to lubricant characteristic at micro-clearance,an integrate viscosity correcting model was obtained when the adsorbent effect of wall and the shear thinning were considered.
根据润滑剂在微间隙下的特性,综合考虑壁面吸附层效应和润滑剂剪切稀化特性,得到简化的综合修正粘度计算模型,并运用此结果进行了薄膜润滑轴承的性能分析,得到各参数与轴承润滑性能的关系。
In the field of rotating machinery online monitoring and remote diagnosis, the demand of vibration signals data reduction is more and more imminently.
旋转机械在线状态监测和远程诊断系统中振动数据实时存储和远程传输对数据稀化、重构技术提出了较高的要求。
Since 1990s,a large amount of precious zoolite and plant fossils have been found in the strata from Haifangou formation to Fuxin formation of Mesozoic era in Western Liaoning Province and the adjacent Daohugou area of Inner Mongolia.
这些珍稀化石被分散描述和报道于国内外的各种期刊、文集及专著中,查找起来多有不便,而且有很多珍稀化石的具体产出层位模糊不清,不便于对比研究。
