  • A comparison between numerical models and measurements in a Kaplan turbine guide vanes
    Lipej, Andrej ...
    In this paper numerical and experimental results of flow analysis in cascade and of flow past a single guide vane are presented. The flow through a cascade and flow past a vane are viscous and ... incompressible and that is why finite element solver of steady and unsteady Navier-Stokes equations has been developed. Recently the solver has been improved for solving turbulent flow, using van Driest mixing length and Baldwin-Lomax turbulent model. For solving the partial differential equations the finite element method with eight nodal isoparametric elements has been used. Large system of equations is solved using front solution method. Velocity distribution was measured by Laser Doppler Anemometer. LDA measurement gives local value of velocities: mean value and rms of velocity fluctuations.
