Hydraulic coupling internal flow visualization and velocity Identification Method

Fluid coupling is mainly depend on the kinetic energy of the working fluid to pass and implement energy transformation hydraulic components. Fluid coupling as transmission components widely used in vehicle transmission, high inertia and high power device startup speed drive on. In many areas of the national economy in the fluid coupling has a broad application prospects. Internal flow fluid coupling is an extremely complex unsteady three-dimensional flow, the internal flow characteristics determine the fluid coupling of external performance. Strengthen internal fluid coupling characteristics of the flow field  Hydraulic adapters  coupling for improving the work performance, to ensure the safety and reliability of its operation is extremely important. With the development of modern science and technology, flow visualization techniques in the study of fluid flow inside the machine has made tremendous progress. Through flow visualization method can be visually observed picture of the internal flow fluid coupling and flow characteristics, can be qualitatively analyzed fluid coupling internal flow field distribution and flow parameters for identification and quantification of extraction. Meanwhile, the flow visualization and flow parameter identification results by the fluid coupling theory of flow field numerical provide test basis. In order to gradually improve the fluid coupling modern design methods, must pass this powerful flow visualization fluid coupling means to carry out the internal flow pattern of research, its internal flow identification,
