Flow-Structure interaction: CFD modelling

Flow-Structure interaction: CFD modelling

IH Cantabria has been researching flow-structure interactions by means od CFD codes (Computational Fluid Dynamics ) for the last fifteen years. The work has focused on adapting the CFD technique, widely used in other engineering fields, to the specific field of coastal engineering as a complementary tool in the design of coastal structures. The purpose of this research is to develop tools to evaluate the functionality and stability of both conventional and innovative coastal structures in the pre - design and design phase.

Through this research we have developed new mathematical models  which take into account not only the wave transformation processes against structures, but also other physical processes that take place, such as flow through granular media forming protection sheets or breakwaters developed turbulent flow wave breaking. Furthermore, numerical algorithms have been developed to
realistically reproduce waves as well as  techniques which which  model wave generation and absorption greatly reducing computational times.
Th
e numerical models developed by IH Cantabria are a result of all this research, both  two-dimensional 
IH-2VOF and  three-dimentional  IH-3VOF  and  IH-FOAM versions.. The  development of these models has been supported by an exhaustive experiemntal validation process as well as field measurements on different types of coastal structures to determine the ranges of validity of the mathematical models and numerical algorithms implemented. The use of of these models has been integrated within the work methodology which allows combining different parts of the design and the marine climate or wave propagation, with new aspects such as climate change .

Further information can be found in indexed journals and international conference papers . The transfer of these models is included in the  developed methodology, which allows cost savings and reduces uncertainty thresholds in the calculations for the design of structures, especially in the case of unconventional structures, which are becoming more commonly used as they take into consideration functional and environmental aspects .
