Recognition of surface profiles for free and forced vortex.

FluidoSurge-X 140 Free and Forced Vortex Apparatus The FluidoSurge-X 140 Free and Forced Vortex Apparatus is a high-quality fluid mechanics lab equipment designed to facilitate in-depth study of free and forced vortex behaviors. Ideal for educational and experimental purposes, this apparatus enables precise analysis of vortex dynamics, including surface profiles, velocity measurements, and angular velocity verification, making it an essential tool in fluid mechanics laboratories. The apparatus features a transparent acrylic cylinder that allows clear visualization of vortex patterns. A free vortex is created as water discharges through interchangeable orifices at the cylinder base, and its profile is measured using a sliding and depth scale. For forced vortex experiments, a paddle rotated by water jets induces the vortex. The resulting profile is then accurately measured using a profile-measuring gauge, ensuring repeatable and reliable results. Additionally, a pitot tube is included to measure velocity at various points within the vortex. Engineered to seamlessly integrate with a hydraulic bench or laboratory water supply, this apparatus offers flexibility and convenience in operation. Overflow cut-outs maintain a constant water level during experiments, while the adjustable measuring components provide enhanced precision in plotting vortex characteristics. This apparatus is a vital teaching aid for educational institutions, allowing students to explore the fundamental principles of fluid dynamics through hands-on experiments. Its robust construction and precise functionality make it a trusted choice for fluid mechanics research.

The experimental set up consist of a circular transparent cylindrical tank, which four circumferential jets have been placed along the circumference of the cylinder near its bottom which helps in the formation of free vortex. It is assumed that the torque exerted by these jets is negligible. The Orifice is reducing bush so that a reduced diameter can be investigated. The plate can also be rotated with the help of a variable speed motor so that the cylinder rotates about its vertical Axis with the help of a V belt and forced vortex is formed. Conditions wear allowed to steady state and the depth of flow at any particular point was observed not to change over a period of time. The experimental procedure involves measurement of resulting free surface that represents the variation of the sum of the pressure and datum head.
