Summary
This work documents the results of a test project conducted in 2013 spanning a period of six
months at the University of Brasilia (UnB) in collaboration with the Anton de Kom University
of Suriname (AdeKUS). The aim of said project was to firstly determine the performance
characteristics of a pico hydro turbine manufactured by Indalma Industries Inc. (3I), a company
based in Brazil. As a second objective, a computational fluid dynamics (CFD) analysis was done
to qualitatively identify, as a first assessment, the regions of flow losses in the turbine, and the
interaction of the stator-rotor transition region. The experimental campaign at UnB yielded the
following results, viz. the performance characteristics of the turbine in terms of the power-, flow-
and e�ciency curves as a function of the rotational speed of the shaft, as well as the turbine’s
specific speed. Moreover, the experimental results provided the boundary conditions for the
CFD analyses. Using the experimental results as a reference (point of departure), the numerical
analyses showed that due to the absence of inlet guide vanes (IGV), high (unquantified) losses
occur within the stator-rotor transition region. Furthermore, given the fact that for this specific
turbine, approximately midway the shroud, it is non-smooth and additionally exceeds the typical
value of 15 degrees for the flow angle, extra, yet avoidable, losses are present.
