Flow under a vertical sluice gate. 5m^3/s with a depth of 0. water flows from under a sluice into a trapezoidal channel having a bed width of 6m, side slope of 2, bed slope of 0. What is an Underflow Gate? An underflow gate, more commonly known as a sluice gate, is a mechanism designed to control water flow in water management systems. These gates are typically made from corrosion-resistant materials like stainless steel or Feb 20, 2026 · A stainless steel sluice valve, also known as a gate or knife gate valve, is a flow-control device designed to start, stop, or regulate the movement of liquids, slurries, or semi-solid materials in piping systems. Unlike standard gates that simply open or close fully, sluice gate valves allow for fine-tuned regulation of water volume and pressure. 036, energy coefficient = 1. Object moved Object moved to here. Jun 1, 2016 · In this paper, two ANN models using the back propagation algorithm were developed to investigate the flow for both free and submerged flow conditions under vertical and inclined sluice gates. These gates are typically made from corrosion-resistant materials like stainless steel or In this article, we will discuss the underflow gate, covering its components, types, flow rate calculation, and applications in various water management systems. . Feb 20, 2026 · Types of Gearbox Sluice Gates A gearbox sluice gate is a critical flow control mechanism used in water management, irrigation, wastewater treatment, and industrial systems. They operate via a flat gate that slides vertically or at a slight angle within a frame, allowing incremental control over water passage. Sluice gates can be used to control and measure volume flow rates in open channels and rivers, mainly in connection to hydro power plants. Study of free-surface flow under sluice gate is important to provide a prediction tool for the optimal management of irrigation and drainage channels. If a hydraulic jump occurs somewhere at the downstream of the sluice gate, compute the flow profile between the vena contracta and the Cd = 0 (1 + 0 r) If water discharges freely through an orifice with both bottom and side contractions suppressed, the flow pattern equals that of the free outflow below a vertical sluice gate as shown in Figure 8. 016m at the vena contracta. 025. The sluice gate is regulated to discharge 11. 01 and n=0. Feb 16, 2023 · In this paper, two open issues concerning the flow under a vertical, sharp-crested sluice gate have been investigated, namely, the instability of orifice flows at sluice gates for high relative openings and the multiplicity of solutions for the partial dam-break problem. The collected information on inclined sluice gates was extracted from Montes [39] and Nago [40]. This paper aims (i) to carry out experimental study of abrupt waves including a dam-break flood wave and sudden release of flow under a sluice gate facing vertical and inclined obstacles in initially dry flumes, and (ii) to investigate the performance of ISPH and FV-VOF methods in simulating the complex behavior of free surface waves. Feb 20, 2026 · A sluice gate valve integrates the robust flow-blocking capability of a traditional sluice gate with the precision control of a valve system. Sluice Gates Sluice gates are linear-motion valves used to precisely manage water levels and flow rates in open channels such as drainage ditches and irrigation canals. By incorporating a gearbox, these gates provide mechanical advantage for opening and closing, ensuring precise regulation of liquid flow under various pressure conditions. Flow through the gate may be free or submerged depending on the tailwater depth. Feb 16, 2023 · The present paper deals with two open issues concerning the free orifice flow under vertical sluice gates, namely, the flow stability at large gate openings and the disambiguation of The present paper deals with two open issues concerning the free orifice flow under vertical sluice gates, namely, the flow stability at large gate openings and the disambiguation of multiple solutions in the case of partial dam-break. These data were for free and submerged flow conditions under vertical sluice gates as well as for inclined sluice gates. When the downstream tailwater increases to the point at which the gate is no longer flowing freely (downstream submergence is causing a greater upstream headwater for a given flow), the Mar 29, 2024 · This paper provides a discharge measurement model for both free and submerged flow in sluice gates with a broad-crested weir, which is based on the direct calibration of discharge coefficient. wrkojuiixnyypcsymhtsovmsvjhqtmvoboyuhuovmrhxe
