Fluid–structure interaction using a partitioned semi-implicit predictor–corrector coupling scheme for the application of large-eddy simulation

Abstract: The paper is concerned with an efficient partitioned coupling scheme developed for dynamic fluid-structure interaction problems in turbulent flows predicted by eddy-resolving schemes such as large-eddy simulation (LES). To account for the added-mass effect for high density ratios of the fluid to the structure, the semi-implicit scheme guarantees strong coupling among flow and structure, but also maintains the advantageous properties of explicit time-marching schemes often used for turbulence simulations. Thus … Show more

“…Moreover, the range of different dimensional models can be utilized effectively by combining them as has been undertaken in recent research studies, with additional challenges being undertaken through domain decomposition and distribution, exchange and conservation of mass, momentum and energy flow across the linkages and consistency in the linked models' parameters across the model common interfaces. The main linking and coupling techniques include direct inputs from point sources without feedback from the hydrological to the hydrodynamic processes (Chen and Hong 2012, Zhang et al 2012, Huang et al 2013, Shrestha et al 2013, explicit linkage with time-step differences and modifications across common interfaces between river and estuary interfaces (Kashefipour et al 2002, 2006, Lai et al 2013, implicit or fully coupling by solving the unified equations for river and estuary interfaces, surface -subsurface interfaces (Gunduz and Aral 2005) and hydrodynamic-sediment particles coupling (Breuer et al 2012, Helmig et al 2013, Park et al 2013.…”

“…Two widely extended projection methods are the node projection method 1 and the quadrature projection method. 43 Projection methods are simple to implement, have been demonstrated to be strictly conservative, and have already been quite successfully used in relevant applications, as for example by Breuer et al 50 analysing an elastic appendix downwind a circular cylinder using LES.…”

“…As drawbacks of these methods, Breuer et al 50 point out the occurrence of non-physical distribution of the loads when the structural mesh is finer than the fluid mesh, and Jaiman et al 47,52,53 refer to some problems related with the accuracy and repeated data transfer of these methods. Also, Jiao and Heath…”
