Characteristics of bladeless turbine

Abstract

The project objective was to perform laboratory tests of the SETUR DVE 120 bladeless turbine and to analyse its measured parameters. Operating characteristics were then determined based on the measured values. The measurement was performed in a closed hydraulic testing circuit in a laboratory of the Department of Mechanical Engineering, Faculty of Engineering, Czech University of Life Sciences Prague. The first part of the article describes the workplace and the method of measurement of the main and the auxiliary parameters. The second part deals with the turbine characteristics. The characteristics describe the relationship between the water flow rate and the usable water gradient and between the water flow rate and the electrical power output of DVE 120, which is important from the user’s point of view. The conclusion features a comparison of the bladeless turbine operating characteristics (dependency of the overall efficiency on the waterpower) and the characteristics of the Francis turbine.
