Abstract

In
the article, there are theoretical and experimental investigations presented
with regards to determination of optimal parameters of the straight-flow
turbine for non-dam hydro power stations.

The
goal for conducting theoretical and experimental investigations is to increase
electric power of the hydro turbine.

The
most optimal angle of attack of the flow direction at the inlet has been calculated.
Accordingly, the results of velocity, pressure, lift and drag forces as well as
lift and drag coefficients along the blade have been received. Also, hydro
turbine’s work with non-rotating and rotating shaft modes have been taken into
account. The achieved results executed in 2D and 3D simulation software modes
allowed visualization of the hydro turbine performance through depicting
arrows, streamlines, contours, surfaces and line graphs.

The
calculations with regards to incompressible liquids were measured with the help
of COMSOL Multiphysics and ANSYS Fluent software packages through application
of Direct Numerical Simulation (DNS) and K-epsilon methods on the base of
Navier-Stokes equations.









Changing
water discharge through a ball valve, the amount of the rotation of the
hydraulic turbine rotor was determined using a tachometer. The produced
electric power due to the rotation of the hydraulic turbine rotor in minutes is
calculated according to Ohm's law.
