We always adopt uniform fluid, separate fluid and drift flow model in multi-phase theory. 多相流理论中经常采用的有均流模型、分流模型及漂流模型。
Experiments with Upward Oil-water Flow Through the Vertical Concentric Annulus. A new and uniform method to express the constitutive equation for analyzing non-Newtonian fluid flow was put forward on the analyses of all items in momentum equation. 为了解决此问题,在分析流体运动方程中各项物理意义的基础上,给出了一种统一的本构方程的书写形式,用于研究非牛顿流体圆管和环空管流层流流动规律。
On the condition of uniform heat input and for temperature dependent properties, the influences of the fluid inlet temperature, heat flux and geometric parameters on the fluid flow and heat transfer in an insert tube were investigated. 获得了恒热流率和变物性条件下的流均分布和温度分布,并考查了流体入口温度、热流率和插入件几何形状对插件管内充分发展的层流流动和传热的影响。
