Next generation algorithms for partitioned fluid-structure interaction Ghent University
An increasing number of applications require the coupling of effects from different physical fields. A leading role is played by the field of fluid-structure interaction, which investigates systems where flow and structural motion cannot be decoupled. Although these phenomena are widespread, their numerical simulation is only moderately used due to the tremendous computational cost and required expert knowledge. The high cost is caused by the ...
Efficient solution of fluid-structure interaction problems in structural dynamics Ghent University
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
Partitioned simulation of fluid-structure interaction and other coupled problems Ghent University
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.
Fluid-structure interaction simulations of wind turbines with composite blades Ghent University
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.

Development of techniques to simulate the interaction between air jets and a flexible, fuzzy yarn Ghent University
Currently, the textile industry is energy-intensive as several processes require compressed air. In this sector, interaction between air jets and a yarn frequently occurs, but this interaction is not yet well understood. Unfortunately, current simulation techniques are too simplified to represent this interaction reliably. State-of-the-art techniques often simplify the flow field or use global coefficients to calculate the forces on the yarn ...
