Fully coupled fluid-structure interaction model of reed valves in a multi-cylinder reciprocating piston compressor

A 3-D Transient CFD Model of a Reciprocating Piston Compressor with Dynamic Port Flip Valves

In this paper a full transient 3-D CFD model of a complete single piston compressor system along with dynamic inlet and outlet port flip valves is presented. The model includes the motion of the cam driven piston, and also predicts the motion of the dynamic flip valves. All activities related to model creation, simulation and postprocessing were performed within the simulation software Simerics...

Fully-coupled fluid-structure interaction simulation of the aortic and mitral valves in a realistic 3D left ventricle model

In this study, we present a fully-coupled fluid-structure interaction (FSI) framework that combines smoothed particle hydrodynamics (SPH) and nonlinear finite element (FE) method to investigate the coupled aortic and mitral valves structural response and the bulk intraventricular hemodynamics in a realistic left ventricle (LV) model during the entire cardiac cycle. The FSI model incorporates va...

Noise Diagnostic Strategies in a Fractional Horsepower Reciprocating Piston Compressor

Fluid Structure Interaction and Impact Analyses of Reciprocating Compressor Discharge Valve

In this paper, Fluid Structure Interaction analysis is conducted to simulate moving mechanism of discharge valve and predict a failure in discharge valve in reciprocating compressor. Moving mechanism of discharge valve, opening and closing, shows impact phenomenon owing to a high velocity correspond to valve motion. The cylinder pressure is successfully validated before conducting impact analys...

NKS for Fully Coupled Fluid-Structure Interaction with Application∗

Newton-Krylov-Schwarz algorithms have been used in many areas and are often quite scalable and robust. In this paper we explore the application of Schwarz type domain decomposition preconditioners to some fully coupled systems for fluid-structure interaction. In particular, we are interested in developing a scalable parallel framework for the simulation of blood flow in human arteries [11]. In ...
