The objective of this work is to develop and implement efficient numerical procedures for gradient based shape design optimization of steady, strongly coupled fluid–structure interaction problems. Nonlinearities in the analysis arise from both the solid behaviour, the fluid behaviour, and from the deformed interface, where the deformation of the interface is large enough to significantly alter ...

Computational Fluid Dynamics is now a new ramification of the numerical discretization method based on high-performance electronic computers, which focuses on fluid mechanics simulation. Fluid mechanics has two main braches that one is theoretical analysis and another is experimental research. Therefore, theoretical and experimental fluid mechanics were created as most important constituents in...

In this work, we consider fluid-structure interaction simulation with nonlinear hyperelastic models in the solid part. We use a partitioned approach to deal with the coupled nonlinear fluid-structure interaction problems. We focus on handling the nonlinearity of the fluid and structure sub-problems, the nearincompressibility of materials, the stabilization of employed finite element discretizat...

In this paper we consider a simplified model for fluid-solid interaction in one space dimension. The fluid is assumed to be governed by the viscous Burgers equation. It is coupled with a finite number of solid masses in the form of point particles, which share the velocity of the fluid and are accelerated by the pressure difference of the fluid on both sides. We prove global existence and uniqu...

We present a simulation framework to integrate several aspects of the combustion and burning process in a unified and modular manner. A simple three gas flame model is used to simulate a combustion process, while air motion is simulated as a single moving fluid. Solid objects inside the simulation domain can catch fire and start burning. Heat information is transferred from the fluid simulator ...

The numerical simulation of multiphysics problems has grown steadily in recent years. This development is due to both the permanent increase of IT resources and the considerable progress made in modeling, mathematical and numerical analysis of many problems in fluid and solid mechanics. The phenomena related to fluid/structure mechanical coupling occurs in many industrial situations, and the in...

Motivated by the desire to investigate vehicle fording scenarios, we analyze four frameworks for the simulation of the fluid-solid interaction problem. While all of these approaches rely on a general multibody dynamics simulation framework that supports impact, contact, and constraint, they differ in (i) the fluid representation; (ii) the simulation methodology; and (iii) the fluid-solid interf...
