The hydrodynamic characteristics of a bent-bar bend in a conveying system is to study its influence on fluid flow behavior. The study of these characteristics is of great significance for optimizing the design and operation of conveying system. The following are some of the research content related to the fluid dynamics characteristics of the bent rod bend in the conveying system: Flow distribution: The bent rod bend causes the change of the fluid flow trajectory, so the study of its influence on the flow distribution is an important content. Through numerical simulation or experimental research, we can explore the flow distribution in the bend area, including the change law of velocity and pressure parameters. Pressure loss: The bend bar elbow introduces a bend in the flow channel, which causes a pressure loss when the fluid flows. Studying the pressure variation in the bend area of the bend allows to assess its contribution to the total pressure loss of the system and to measure its impact on the energy efficiency of the transmission. Vortex formation and resistance: The presence of the elbow will cause the formation of vortices, which will increase the resistance of the system. The eddy current structure and characteristics of the bend area can reveal its contribution to the resistance of the system, and provide the basis for the measures to reduce the resistance. Solid-liquid separation effect: there may be suspended particles in the transported liquid, and the flow characteristics of the bend area will affect the solid-liquid separation effect. The solid-liquid separation performance of the conveyor system can be optimized by studying the deposition, suspension and removal of particles in the bend area. Flow stability and turbulence characteristics: rod bends can cause flow instability, resulting in the generation and development of turbulence. The study of the flow stability and turbulence characteristics of the bend area is helpful to understand the physical behavior of the fluid and the corresponding dynamic mechanism. The above are some contents of the research on the hydrodynamic characteristics of the bend rod in the conveying system. These studies can be carried out by experiment, numerical simulation, theoretical analysis and other methods, aiming to deeply understand the influence mechanism of the bend bar elbow, and provide scientific basis for its optimal design and system operation.
