Ventilation and hydrodynamic CFD studies

Computational fluid dynamics (CFD) is a set of numerical models that use conservation equations, turbulence models, etc., which, converted into computer tools, are usually used in engineering to simulate the behaviour of fluids including their movement, heat and mass transfer ...

What is it for?

CFD tools are used in many branches of engineering and have very diverse applications, such as Aerodynamics in aviation and motorsports or the design of cooling of electrical circuits or in Hydraulic Engineering for the design of networks, channels, pipes ...


At SUEZ we use CFDs for the evaluation and optimization of ventilation systems in process buildings, the calculation of emissions in product storage tanks or the calculation of ambient air quality at a microscale.


We offer integral services for industrial ventilation and gas treatment systems. We take care of calculating and optimizing your ventilation system through CFD, the design and installation of the piping and the gas treatment system.

Hydrodynamic Modeling

Hydrodynamic models are a key evaluation tool to simulate the behaviour of water masses and we are specialists in modeling any environmental matrix. Water is our origin.

In the maritime field in particular, the modeling of water masses in the design of harbors, studies on the effect of the construction of submerged breakwaters or dredging works, the impact of discharges from an underwater outfall, the study of thermal plumes, fuel spills, etc. In rivers, the impact of various types of construction (bridges, breakwaters), dam breaks, flood studies, the transport of tracers, etc.

For this, we use the TELEMAC model, based on the philosophy of open source software and with a large community of users. It presents different versions, 2D and 3D


With this system we can also configure future scenarios and possible accidents with risk of water contamination.

The system allows to make videos with the results of the modeling for a set time interval, thereby knowing the theoretical evolution of an effluent, reactive or passive, and obtaining valuable information on the measures to be adopted based on the time elapsed since the spill was started.

The hydrodynamic model is essentially fed with bathymetry, tidal and meteorological data, and in its case, effluent data.
