A robust immersed boundary-lattice boltzmann method(IB-LBM)is proposed to simulate fluid-structure interaction(FSI)problems in this *** with the conventional IB-LBM,the current method employs the fractional step technique to solve the lattice boltzmann equation(LBE)with a forcing ***,the non-physical oscillation of body force calculation,which is frequently encountered in the traditional IB-LBM,is suppressed *** is of importance for the simulation of FSI *** the meanwhile,the no-slip boundary condition is strictly satisfied by using the velocity correction ***,based on the relationship between the velocity correction and forcing term,the boundary force can be calculated accurately and easily.A few test cases are first performed to validate the current ***,a series of FSI problems,including the vortex-induced vibration of a circular cylinder,an elastic filament flapping in the wake of a fixed cylinder and sedimentation of particles,are *** on the good agreement between the current results and those in the literature,it is demonstrated that the proposed IB-LBMhas the capability to handle various FSI problems effectively.

China Ocean Engineering 2019年第6期33卷 637-648页

作者： CONG Long-fei TENG Bin State Key Laboratory of Coastal and Offshore Engineering Dalian University of Technology

The existence of the heaving plates can improve the heaving motion performance of an offshore structure significantly by providing both extra added mass and *** the current research,numerical investigation is carried out on the hydrodynamic characteristics of both isolated square heaving plate and double square heaving plates with opening by an immersed boundary-lattice boltzmann *** effects on hydrodynamic performance of plates due to Keulegan-Carpenter(KC)number,frequency number,opening ratio,opening distribution and spacing of plates are *** is found that the heaving plates with optimized opening ratio can provide additional damping compared with the plates without *** hydrodynamic characteristics of double plates can be obtained with the increase of plate spacing.

Fluid-structure-interaction problems are ubiquitous,complicated,and not yet well *** this paper we investigate the interaction of a leading rigid circular cylinder and a trailing compliant filament and analyze the dynamic responses of the filament in the wake of the *** is revealed that there exist two flapping states of the filament depending on the cylinder-filament separation distance and the relevant critical distance distinguishing the two states is associated with the Reynolds number and the filament *** is also found that the drag coefficient of the cylinder is reduced but that of the filament may be increased or decreased depending on its *** with a single filament in a uniform flow,the filament of the same mechanical properties flapping in the wake of the cylinder has a lower frequency and a greater amplitude.
