Francis Turbine
The Francis Turbine is a reaction turbine. It is the most common turbine in the world, due to its ability to work for a wide range of applications. Its moving part (runner) is a radial impeller.
In this video students from Nottingham Trent University asked the research topic "Do variations in the temperature of water in a Francis Turbine operated hydro plant, due to differences in climates worldwide, significantly affect the efficiency?" They predicted that it would not significantly affect the efficiency of the turbine, watch to find out if they were correct.
The students in this video look at the effects of temperature on viscosity, and explain step by step their research process, including how they set up their experiment using TecQuipment's Francis Turbine experiment that mounts on the Hydraulic Bench - clip of it running can be found at 1.49. The group also 3D printed their own adapter for the heater to connect to the Francis Turbine.
This was an entry in the TecQuipment 2020 Student Competition. Team 13 members: Ellie Solomon, Adrian Osei-Bonsu, Ethan Coke and Taran Garewal.
