In this project computational methods will be developed that can be used for fluid-structure interaction computations for rather slender and lightweight structures under wind loading conditions. This computational technique will allow for studies of ovalling of silos, flutter of bridges, excitation of flexible pipes by vortex shedding, galopping of cables, U+2026
The researcher will develop coupling algorithms for the partitioned simulation of fluid-structure interaction (FSI) problems with nonlinear behaviour, for example with contact between the different parts of the structure. The second goal is to reduce the duration of FSI simulations. Finally, the influence of a difference in time discretization between the flow solver and the structural solver will be analyzed.
As the length of composite blades for large horizontal axis wind turbines keeps on increasing, the interaction between the air flow and the deforming composite blades has to be taken into account during their design. Therefore, a detailed numerical model and faster simulation techniques will be developed. Using this model, we will study vibrations and defects in the composite material.
Reducing flow-induced vibration in steam generators and heat exchangers using two-phase fluid-structure interaction simulations Ghent University
Steam generators and heat exchangers are omnipresent in industrial heating, chemical industry and power plants. These devices often consist of a cylindrical barrel filled with a bundle of long and slender cylindrical tubes. The barrel of a steam generator contains a mixture of water and steam and consequently the tubes in the barrel are surrounded by a so-called two-phase flow. Similar two-phase flows are present inside or outside the tubes ...
Improving efficiency and safety of devices with flow along cylinders using fluid-structure interaction simulations (ESFLOC) Ghent University
Flows along cylinders occur in heat exchangers, air-jet looms and reactors. However, the vibration of these cylinders due to interaction with the flow is not fully understood. To improve the efficiency and safety of these devices, insights will be developed about multiple flexible cylinders in axial flow, supersonic flow along a cylinder and multi-phase flow along a cylinder.

Patient specific fluid structure interaction modelling of aortic coarctation. Pre- and post-operative numerical study of biomechanical loads and ultrasonic imaging of the pathological aorta. Ghent University
Aortic coarctation is a congenital narrowing of the descending aorta. As it obstructs blood flow, it needs to be treated as soon as possible (shortly after birth). The aim of this project is to find an optimal (patient-specific) treatment based on biomechanical loads calculated through fluid structure interaction. This project also focuses on quantifying wave reflections and imaging techniques such as MRI and 3D Ultrasound.
In navigation areas with bottoms covered by a thick fluid mud layer, deep-drafted ships may be allowed to sail at a limited vertical distance above the mud-water separation , and sometimes ships even sail through the mud. This causes a very intense interaction between the water column, the mud layer and the ship. The purpose of this project is to develop a numerical methodology to calculate the interaction between water, mud and a moving ...
