Hydrodynamics considers the relationship between the trajectory, the outlet contour and the outlet velocity during flow from tanks.
HM 150.09 allows a user to study and visualise the profile of a water jet. Additionally, the discharge coefficient can be determined as a characteristic for different contours.
The experimental unit includes a transparent tank and a point gauge with scale for visualising the jet paths. An interchangeable insert is installed in the tank’s water outlet to facilitate the investigation of various openings. Four inserts with different diameters and contours are provided along with the unit.
To visualise the trajectory, the issued water jet is measured via a point gauge that consists of movable rods. The rods are positioned depending on the profile of the water jet. By means of the scale, the trajectory can be determined.
The tank contains an adjustable overflow and a scale. In this way, a precise adjustment and accurate reading of the fill level are possible. The experimental unit is positioned easily and securely on the work surface of the HM 150 base module. The water is supplied and the flow rate measured by HM 150. Alternatively, the experimental unit can be operated by the laboratory supply.
In order to perform a virtual analysis of flow behaviour, CFD simulations are often used in practice. Such simulations allow, for example, flow visualisations in areas that cannot be visualised experimentally. In the GUNT Media Center, flow visualisations based on CFD calculations are available online. There are also multimedia teaching materials including E-Learning courses on basic knowledge and calculations. Videos show a complete experiment with preparation, execution and evaluation. Worksheets with solutions supplement the teaching material.
