This work deals with fluid-structure interaction (FSI), one of the emerging areas numerical simulation and calculation. research shows a study investigating heat transfer enhancement in circular finned tube by using alumina nanofluid as working fluid typical twisted tape that has twisting ratio 1.85. The studied volumes fraction are φ=0, 3, 5 % under conditions laminar turbulent flow. solution ...

We present a monolithic approach to large-deformation fluid-structure interaction (FSI) problems that allows for choosing fully implicit, single-step and single-stage time integration schemes in the structure and fluid field independently, and hence is tailored to the needs of the individual field. The independent choice of time integration schemes is achieved by temporal consistent interpolati...

Abstract In this study the isogeometric B-Rep mortar-based mapping method for geometry models stemming directly from Computer-Aided Design (CAD) is systematically augmented and applied to partitioned Fluid-Structure Interaction (FSI) simulations. Thus, newly proposed methodology geometries described by their Boundary Representation (B-Rep) in terms of trimmed multipatch Non-Uniform Rational B-S...

Effect of arterial wall compliance on the invasive coronary diagnostic parameters for various severities of coronary stenoses was assessed. The Mooney-Rivlin model was used to define the non-linear properties of the arterial wall and the plaque regions. The nonNewtonian viscosity of blood was modeled using the Carreau model. A finite element method was employed to solve the pulsatile fluid (blo...

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...

A method is presented for studying and quantifying the biomechanical behavior of the human eye under elevated fluid and structural pressure loading. The approach taken involves a coupled synergistic computer modeling and experimental effort in which numerical models are used to predict the biomechanical response of eye under pressure, and physical cadaveric eye models along with appropriate ima...

Hydraulic valves are key components of fluid power systems. They control the flow rate and pressure in hydraulic lines, actuator motion, direction. Valves that or can be divided into two main categories: spool-type valves, where similar to piston inside a sleeve with orifices; seat-type which poppet seat opens closes flow. Forces induced on valve during oil crucial valve’s operational capabilit...

Abdominal aortic aneurysm (AAA) rupture is the clinical manifestation of an induced force exceeding the resistance provided by the strength of the arterial wall. This force is most frequently assumed to be the product of a uniform luminal pressure acting along the diseased wall. However fluid dynamics is a known contributor to the pathogenesis of AAAs, and the dynamic interaction of blood flow ...

The dynamics of cavitation bubbles and their interaction with solids has been studied for long, mostly on the macro-scale sheet vortex cavitation. Erosion takes place small, concentrated areas solid walls exposed to One-way fluid structure (FSI), in which feedback material deformation is not considered, provides an adequate understanding underlying mechanism. However, practical applications mot...
