Internal Hydraulics of Thermal Discharge Diffusers

Fluid movement in a flat pipe with a break

“…To account for these factors, it is necessary to consider the task of at least a two-dimensional formulation, applying the methods of jet theory. In all cases, conformal mappings of some canonical region were built [10][11][12] ‫ݑ(‬ = ߦ + ݅߫; usually, such areas are the half-plane, square, circle, strip, sector, etc.) to the region of the complex potential ‫ܩ‬ ௪ (where ‫ݓ‬ = ߮ + ݅߰ complex potential) and the flow area ‫ܩ‬ ௭ ‫ݖ(‬ = ‫ݔ‬ + ‫,)ݕ݅‬ or the area of the speed of the speed‫ܩ‬ :…”

“…From formula (3), it suggests that the point ‫ݑ‬ = ݁ ఈ బ గ , in which the cavity tangent to the boundary parallel to the BD wall is determined from the equation , the solution to this task is simplified. In particular, from equation (11), neglecting small higher orders, we define a point in which the cavity tangent is parallel to the BD wall [32]:…”

Control of flow in the side outflow channel

“…In the gaps between the compressed section and the walls of the nozzle, a vortex zone is formed, where there is a process of erosion of the channel and deposition of particulate matter sediments (for example, when the water from Amudarya to the Karshin main canal these zones are filled with sediments, and the drainage channel is buried). [3][4][5][6][7] The pressure losses in the water distribution channels are mainly from losses to sudden expansion after the flow compression (in the nozzle). Therefore, the definition of the shape of the non guide surface of the water distribution channel is of great importance in the design of hydraulic facilities.…”
