Application of a strong FSI coupling scheme for the numerical simulation of bileaflet mechanical heart valve dynamics: study of wall shear stress on the valve leaflets [PDF]

, 2012
One of the major challenges in the design of Bileaflet Mechanical Heart Valves (BMHVs) is reduction of the blood damage generated by non-physiological blood flow.

Research on thermal-fluid-structure coupling of valve plate pair in an axial piston pump with high pressure and high speed

Industrial Lubrication and Tribology, 2018
Purpose High pressure and high speed of the axial piston pump can improve its power density, but they also deteriorate the thermal-fluid-structure coupling effect of the friction pairs.

A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact

, 2018
A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-alpha scheme are used for the spatial and temporal discretization.
