Description: 摘 要:基于材料的各向同性理论,根据应力—应变增量关系,建立了一个混凝土的三维本构关系模型。采用
了目前较为成熟的Ottosen的破坏准则,利用了Sargin的单轴应力—应变关系,并在三维增量非线性关系中引入等
效单轴切线模量。所用的模型中的参数是根据前人的经验和实验来取定的。通过对混凝土的各向受拉、受压和拉
压结合的分析表明,所建立的模型较为简单、实用。-Abstract : Based on the theory of isotropic material, according to the stress-strain increment, the establishment of a concrete three-dimensional constitutive models. Using a more mature now Ottosen damage criteria Sargin use of the uniaxial stress-strain relationship, and three-dimensional non-linear relationship incremental introduction of the equivalent uniaxial tangent modulus. By using the model is based on the parameters of the literature and experimental experience to the admission. Right through to the concrete in tension, compression and tensile combining the analysis shows that the model is simple and practical.

Description: 利用CFD软件，采用雷诺应力模型分别计算了300型和250型水力旋流除砂器的内流
场，得到了2种水力旋流除砂器的轴向、径向、切向速度及压强的分布曲线。通过对所得结果的
分析，发现模拟结果基本符合旋流除砂器的运行规律。比较2种旋流除砂器的内流场，表明改进
的300型水力旋流除砂器的结构及分离能力优于原来250型水力旋流除砂器，为水力旋流除砂器
的优化设计和选型提供了可靠的设计依据。-use CFD software, Reynolds stress model used to calculate the respective 300-and 250-type sander hydrocyclones the flow field, been two kinds of hydrocyclones sander axial, radial and tangential velocity and pressure in the distribution curve. Based on the results of the analysis, the simulation results are consistent with the Cyclone sander operating rules. Comparing two kinds of Cyclone sander within the flow field, show improved 300 Desanding Hydrocyclones the structure and separation capacity than the original 250-hydrocyclone sander, Desanding Hydrocyclones for the optimum design and selection provided a reliable basis for the design.
