Abstract: the instrument constants and the introduction of Reynolds number information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The measuring tube fluid flow often must understand its flow state, velocity distribution, etc. Reynolds number is the characterization of fluid flow characteristics of an important parameter. The inertia force of fluid flow in Fg and viscous force ( The friction force) Fm is referred to as the Reynolds number. Use symbols. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a instrument constants and articles about the details of the Reynolds number. The measuring tube fluid flow often must understand its flow state, velocity distribution, etc. Reynolds number is the characterization of fluid flow characteristics of an important parameter. The inertia force of fluid flow in Fg and viscous force ( The friction force) Fm is referred to as the Reynolds number. Use symbols Re said. Re is a dimensionless quantity. Viscous effects of similarity criterion in fluid mechanics. In honor of O. Renault and naming, as Re. Re =ρ 六世/μ ρ; μ; As the fluid density and dynamic viscosity, v, L for the characteristic length and velocity of the flow field. To outflow question, v, L usually take far ahead to flow velocity and the main body size ( Such as wing exhibition or ball diameter) ; Flow problem is within the channel and average flow velocity and channel diameter. Said Reynolds number effects on fluid inertia force and viscous force of micelle [ 1] The ratio of the. Two geometric similar flow field of the Reynolds number are equal, the corresponding ratio of the inertia force and viscous force of micelle is equal. The smaller the Reynolds number means that the more significant effect on viscous force, is the bigger the inertial force effect is significant. The flow of the Reynolds number is small ( Such as lubricating film flow) , its viscosity influence throughout the whole flow field. The flow of the Reynolds number is very big, Such as general aircraft flow around) , its viscosity influence only on the surface or near the boundary layer is important in the wake. In relation to the influence of viscous fluid mechanics experiment, the Reynolds number is the main similarity criterion. But many of the Reynolds number is far less than the Reynolds number of physical model experiment, and the correction method and the development of high Reynolds number experiment equipment is an important topic of the fluid mechanics experimental research. Reynolds number is small, means that the fluid flow in the viscous force between particles dominate, fluid particle flow parallel to the pipeline wall regularly, a laminar flow state. Reynolds number is large, means that the inertial force dominate, the fluid is turbulent flow state, general pipeline Re< Reynolds number; 2000 for laminar flow state, Re> 4000 for the turbulent state, Re = 2000 ~ 4000 for the transition state. Under the different flow state, the motion of the fluid. The distribution of flow velocity is different, average flow velocity of fluid and the pipe & upsilon; With big velocity zui & upsilon; The ratio of Max is also different. So the size of the Reynolds number determines the viscous fluid flow characteristics. When external conditions geometric similarity, Geometric similar tube, fluid flows through the geometric similar objects, etc. ) , if they equals the Reynolds number, the fluid flow and geometry similar ( Fluid dynamics) 。 A similar rule is the base of the flow measurement standardization of throttling device. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
