Fluid‐Structure Interaction Using LES ‐ A Partitioned Coupled Predictor‐Corrector Scheme

A semi-implicit coupling technique for fluid–structure interaction problems with strong added-mass effect

“…By implicit treatment of the added-mass term (pressure stress), the semi-implicit method maintains the favorable stability of the implicit schemes, while explicit treatment of the other terms helps avoiding excessive computational cost [17]. A very similar method was also proposed by Breuer et al [18,19] to solve FSI problems with turbulent flow. An analogous idea is present in the hybrid monolithic-partitioned method of Grétarsson et al [20] for FSI problems with compressible flow.…”

“…Besides, there are many unaddressed questions concerning different aspects of the semi-implicit coupling methods that require more work and attention. Some semi-implicit methods in the literature implicitly couple the dynamic mesh step of the fluid [18,19], while others only explicitly couple it [17,21,22]. However, to the best of our knowledge, there has been no study that evaluates the effect of this modification on the overall performance and accuracy of the semi-implicit coupling method.…”

Scour monitoring via turbulent open channel flow

“…This is required to determine the dynamic response of a structure to both large and small scale turbulent eddies (low and high frequency incident forces). Only large eddy simulation (LES) or direct numerical simulation (DNS) methods are available to fully capture the velocity field [7]. These models, however, require significant computational time and resources, even without considering the structural analysis components.…”
