The Free and Forced Vortex Apparatus FluidoSurge-X 140 is designed for experimental study of vortex motion in fluid mechanics laboratories. It enables generation and measurement of both free and forced vortices under controlled conditions. The apparatus supports surface profile measurement and velocity determination within the vortex. It is intended for academic teaching and experimental verification of vortex flow theory.


Product Overview

The SCIENTICO Free and Forced Vortex Apparatus FluidoSurge-X 140 consists of a transparent acrylic cylindrical vessel mounted for use on a hydraulic bench. A free vortex is generated by allowing water to discharge through an interchangeable central orifice at the base of the vessel. The resulting surface profile is measured using a sliding depth scale. A forced vortex is created by directing water jets through tangential inlet tubes that impinge on a rotating paddle located at the center of the vessel. The surface profile of the forced vortex is measured using a profile measuring gauge, while velocity at any point can be determined using the supplied Pitot tube.

Q1. What is the difference between free and forced vortex in this apparatus?
A free vortex is generated by water discharging through a central orifice, while a forced vortex is produced by tangential inlet jets driving a paddle.

Q2. How is the vortex surface profile measured?
The surface profile is measured using an adjustable profile measuring gauge mounted above the vessel.

Q3. Can velocity be measured inside the vortex?
Yes, a Pitot tube is supplied to measure velocity at different positions within the vortex.

Q4. How is constant water level maintained during experiments?
Overflow cut outs in the reservoir ensure a constant water level during operation.

Q5. What water supply is required for operation?
The apparatus can operate using a hydraulic bench with closed water circuit or a laboratory water connection.
