With wind farms being installed in areas of increasingly complex flow, either imparted by the terrain, by the presence of nearby obstacles or by thermodynamic effects inherent to the local climate, the understanding and prediction of these phenomena has gained paramount importance.
As a leading wind energy consultancy firm, MEGAJOULE must therefore be equipped with the correct tools to be able to correctly assess the wind characteristics at these sites, in order to advise the client on how to maximize production and minimize down-times and maintenance costs.
Since its creation, MEGAJOULE Inovação
has established strong ties with university institutions to better bolster its R&D projects. From its partnership with ISEP
comes the first exciting output: a new CFD solution developed specifically for wind engineering by a team with over 15 years experience in CFD development. The software code WindieTM
is owned by the company Windie Lda
and an exclusive partnership between Windie Lda and MEGAJOULE allows us the use and joint development of the CFD code.
We believe WindieTM
is the most advanced CFD code for wind engineering presently available incorporating a number of distinguishing features:
- Advanced forest canopy modelling, with vertical tree description and horizontal interpolations to better capture complex wooded areas.
- Coupling with mesoscale models which allows for much more representative boundary conditions
- Capturing of thermal effects through full solution of temperature equation, fed by mesoscale data
- Buoyancy and Coriolis effects included

The site assessment studies performed with this new CFD tool are more valuable than other current approaches, due to the correct prediction of separated flow regions and other hazardous flow features. The effects of turbulence, produced through either mechanical or thermal mechanisms, as well as the impact of wind shear and flow inclination, are accounted for to obtain three-dimensional aspects of the flow and provide insight in the micro-siting of wind farm layouts.
It is a crucial part of our service to interpret these results and extract from them the most relevant data to present to our clients, be it virtual time series at layout positions, or direction-averaged data for a more general picture.
As WindieTM is an in-house code, MEGAJOULE Inovação can offer complete versatility in the type of analyses and outputs that can be performed, to better satisfy the requirements of each project.
Our CFD code is constantly under development, following our strong commitment to innovation and research. Currently, we are:
Further developing our meso-microscale coupling techniques, Implementing an advanced turbine wake model, Improving compatibility of inputs and outs with other wind engineering tools.
