Available in PDF, EPUB and Kindle. Book excerpt: Methods for analysis of fluid-structure interaction using high fidelity simulations are critically reviewed. First, a literature review of modern numerical techniques for simulation of aeroelastic phenomena is presented. The review focuses on methods contained within the arbitrary Lagrangian-Eulerian (ALE) framework for coupling computational fluid dynamics codes to computational structural mechanics codes. The review treats mesh movement algorithms, the role of the geometric conservation law, time advancement schemes, wetted surface interface strategies, and some representative applications. The complexity and computational expense of coupled Navier-Stokes/structural dynamics simulations points to the need for reduced order modeling to facilitate parametric analysis. The proper orthogonal decomposition (POD)/Galerkin projection approach for building a reduced order model (ROM) is presented, along with ideas for extension of the methodology to allow construction of ROMs based on data generated from ALE simulations.

Download or read book A New Fluid structure Interaction Point projection Method written by Philip Robert Ivancic and published by . This book was released on 2014 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new point-projection method was developed to transfer loads and displacements in a two-way coupled fluid-structure interaction problem. The existing method involved projecting the load at each computational fluid dynamics (CFD) node onto a corresponding computation structural dynamics (CSD) element. The load is distributed to the CSD nodes on that element. However, the solution is not unique and will vary the projection. In the new method, a rigid pyramid element is built upon the CSD element and that encompasses the CFD node. Thus, the CFD load will be uniquely distributed to the CSD nodes. After the CSD code updates the CSD node location, the pyramid element can also be used to update the location of the CFD node. This work describes a FORTRAN routine that coupled LS-DYNA to Loci/BLAST and tests conducted to test the validation, work conservation, and robustness of the routine.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical technique for the simulation of fluid-structure interaction of airfoils and turbomachinery configurations is presented. The unsteady structural and fluid dynamics equations are discretized by a finite volume technique which is second order accurate in space along with a dual time step scheme that is second order accurate in time. The momentum conservation equation for the solid is written in terms of the Piola-Kirchhoff stresses and the displacement velocity components. The stress tensor is related to the Lagrangian strain and displacement tensors using the St. Venant-Kirchhoff constitutive relationship. Multiple mesh motion techniques are explored. Various smoothing techniques are explored in the solid domain, specifically second and fourth differences and hourglass resistance. Source terms at the surface of the solid are included to account for surface pressure and body forces. Validation of the structural solver is performed using a two dimensional cylinder flag problem. Validation and Verification of the aeroelastic solution procedure is presented for the AGARD 445.6 I-Wing. Finally a validation case is described for a 1 1⁄2 stage transonic gas turbine.

Book excerpt: This book presents state-of-the-art lectures on complex flows of fundamental and industrial interest in the subsonic, supersonic and hypersonic regimes. Experimental investigations of unsteady separated flows, high-enthalpy flows, 3D configurations, laminar and transitional flows are addressed. Theoretical predictions of aerodynamic performances are provided along with analyses of supersonic combustion, detonation, simulation of reactive mixing layer and non-equilibrium flow. Computational Fluid Dynamics methods for the simulation of viscous compressible flow, inviscid viscous flow interactions, real-gas effects in rarefied flow, flows about bodies with permeable walls and supersonic turbulent flows are finally developed and analysed.

This book was released on 2013-03-09 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with mathematical modelling of supersonic and hyper sonic flows about bodies. Permanent interest in this topic is stimulated, first of all, by aviation and aerospace engineering. The designing of aircraft and space vehicles requires a more precise prediction of the aerodynamic and heat transfer characteristics. Together with broadening of the flight condition range, this makes it necessary to take into account a number of gas dynamic and physical effects caused by rarefaction, viscous-inviscid interaction, separation, various physical and chemical processes induced by gas heating in the intensive bow shock wave. The flow field around a body moving at supersonic speed can be divided into three parts, namely, shock layer, near wake including base flow, and far wake. The shock layer flow is bounded by the bow shock wave and the front and lat eral parts of the body surface. A conventional approach to calculation of shock layer flows consists in a successive solution of the inviscid gas and boundary layer equations. When the afore-mentioned effects become important, implementation of these models meets difficulties or even becomes impossible. In this case, one has to use a more general approach based on the viscous shock layer concept.
