| description | The aerodynamic analysis of a wind turbine represents a very complex task since it involves
an unsteady three-dimensional viscous flow. In most existing performance-analysis methods,
wind turbines are considered isolated so that interference effects caused by other rotors or by
the site topology are neglected. Studying these effects in order to optimize the arrangement
and the positioning of Horizontal-Axis Wind Turbines (HAWTs) on a wind farm is one of the
research activities of the Bombardier Aeronautical Chair. As a preliminary step in the
progress of this project, a method that includes some of the essential ingredients for the
analysis of wind farms has been developed and is presented in the paper. In this proposed
method, the flow field around isolated HAWTs is predicted by solving the steady-state,
incompressible, two-dimensional axisymmetric Navier-Stokes equations. The turbine is represented
by a distribution of momentum sources. The resulting governing equations are
solved using a Control-Volume Finite Element Method (CVFEM). This axisymmetric implementation
efficiently illustrates the applicability and viability of the proposed methodology,
by using a formulation that necessitates a minimum of computer resources. The axisymmetric
method produces performance predictions for isolated machines with the same
level of accuracy than the well-known momentum-strip theory. It can therefore be considered
to be a useful tool for the design of HAWTs. Its main advantage, however, is its capacity to
predict the flow in the wake which constitutes one of the essential features needed for the
performance predictions of wind farms of dense cluster arrangements. |
