  1. 1. CFD of Air Flow in Hydro Power Generators

    Author : Pirooz Moradnia; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OpenFOAM; MultipleReferenceFrame; CFD; Generator; Launder-Sharma k-ε;

    Abstract : The air flow through a generator has been numerically investigated with different rotor and stator designs to give a better understanding of the flow for cooling purposes. A simple rotor design has been chosen to start with, and modified through a set of changes, where stepwisemodifications have been imposed to the design of the rotor and the stator. READ MORE

  2. 2. Prediction of Cooling Air Flow in Electric Generators

    Author : Pirooz Moradnia; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

    Abstract : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. READ MORE
