Design and CFD Analysis of Conical Shape Draft Tube

Vikas Rai | Nishant Vibhav Saxena [2]


Abstract: For power generation, in medium head hydro power plants, reaction turbines are used. Water leaving the reaction turbine has high kinetic energy and low pressure energy. To recover the energy, draft tubes at exit of runners are used. Conical draft tube are the simplest form of draft tube and it has high efficiency. In the present work, geometric modeling of a conical shape of draft tube has been done. Meshing has been done in ICEM CFD. Various parameters have been found out for a specified boundary conditions. . From results it has been found that as the water moves out of the draft tube, kinetic energy of water is reduced and pressure energy is recovered.
