CFD modelling of environmental flows

CFD modelling of environmental flows

Within this line of work, open in recent years, there have been advances in the application of CFD models (Computational Fluid Dyanmics) to environmental flows as a new element for the study of hydrodynamic processes studying their influence on processes derived from these flows.

IH Cantabria's research activity has focused on  hyperdense plumes within the project "Development and implementation of a methodology for reducing the environmental impact of brine discharge from desalination (045/RN/08/03.3)" funded by the Spanish Ministry of Environment, Rural and Marine Affairs. In this project, and using CFD technique, we have characterized the behavior of hypersaline effluents in the receiving environment. Numerical modeling has been validated by means of laboratory testing using laser anemometry (PIV Particle Image Velocimetry) and  LIF (Laser Induced Fluorescence) at IH Cantabria. these techniques have helped determine the ranges of uncertainty that exist in numerical modeling.

Using CFD techniques to study hypersaline discharges flow allow a cmore comprehensive characterisation of the flow than that obtained through integral models, as they minimize the initial hypothesis assumed for the flow regarding its behaviorl and dilution. Additionally, CFD techniques allow considering more complex configurations such as multi port disposal systems or interactions between the different ports, whose treatment has traditionally been done through laboratory tests or highly simplified formulations with high uncertainty ranges.
