Numerical Simulation of Fluid-Structure Interaction in Human Phonation
Fluid-structure interaction in a simplified two-dimensional model of the larynx is considered to study human phonation. The flow is driven by an imposed pressure gradient across the glottis and interacts with the moving vocal folds in a self-sustained oscillation. The flow is computed by solving the 2D compressible Navier–Stokes equations using a high order finite difference method, which has b...
متن کاملNumerical Simulation of Fluid-Structure Interaction Using Modified Ghost Fluid Method and Naviers Equations
In this work, we deal with the 1D compressible fluid coupled with elastic solid in an Eulerian-Lagrangian system. To facilitate the analysis, the Naviers equation for elastic solid is cast into a 2×2 system similar to the Euler equation but in Lagrangian coordinate. The modified Ghost Fluid Method is employed to treat the fluid-elastic solid coupling, where an Eulerian-Lagrangian Riemann proble...
متن کاملNumerical Simulation of Fluid-Structure Interaction on Wedge Slamming Impact Using Particle Method
Abstract—This paper presents a fully Lagrangian coupled Fluid-Structure Interaction (FSI) solver for simulations of fluid-structure interactions, which is based on the Moving Particle Semi-implicit (MPS) method to solve the governing equations corresponding to incompressible flows as well as elastic structures. The developed solver is verified by reproducing the high velocity impact loads of de...
متن کاملNumerical simulation of a 3D Bileaflet Mechanical Heart Valve using Fluid-Structure Interaction
Because of their long life span and durability, Bileaflet Mechanical Heart Valves (BMHV) are preferred for valve replacement. However, current BMHV designs induce calcification and thromboembolism, which is believed to be due to non-physiological flow and turbulence generated by the valve leaflets. Therefore, numerical flow simulations can provide relevant information for design optimization [1...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
