Available in PDF, EPUB and Kindle. Book excerpt: This research is aimed at simulation of the aerodynamics/dynamics of large parafoils. Parallel computation methods for 3D simulation of the dynamics and fluid dynamics of a parafoil, with prescribed, time-dependent shape changes were studied. The mathematical model was based on the time-dependent, 3D Navier-Stokes equations governing the incompressible flow around the parafoil, and Newton's law of motion governing the dynamics of the parafoil, with the aerodynamic forces acting on the parafoil, calculated from the flow field. The computational methods developed for these 3D simulations include a stabilized space-time finite element formulation to accommodate for the shape changes, special mesh generation and mesh moving strategies developed for this purpose, iterative solution techniques for the large, coupled nonlinear equation systems involved, and parallel implementation of all these methods on scalable computing systems.

This book was released on 2018-07-09 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a final report as far as our work at University of Minnesota is concerned. The report describes our research progress and accomplishments in development of high performance computing methods and tools for 3D finite element computation of aerodynamic characteristics and fluid-structure interactions (FSI) arising in airdrop systems, namely ram-air parachutes and round parachutes. This class of simulations involves complex geometries, flexible structural components, deforming fluid domains, and unsteady flow patterns. The key components of our simulation toolkit are a stabilized finite element flow solver, a nonlinear structural dynamics solver, an automatic mesh moving scheme, and an interface between the fluid and structural solvers; all of these have been developed within a parallel message-passing paradigm.

This book was released on 1996 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. In the coming years, there will be many changes in the fields of parallel modelling and simulation. High Performance Computing and Networking (HPCN) has now come to the fore. There will be a huge expansion of application areas where it will become important, if not a must, to solve complex problems even faster but still in a cost-effective way.The title of this book reflects the rapid progress that is currently occurring in the field of HPCN with respect to processing power/relatively cheap, high speed networking over long distances.HPCN is now moving into many different areas of application and this is shown by the diversity of topics within this volume - including topics of immense significance for society.The quality of the articles is high due to a strict refereeing process. The reader is given a valuable opportunity to learn about the latest thinking in this field.

This book was released on 2018 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modeling of the ram-air parachute presents challenges in the prediction of the inflight geometry, as there is a strong interaction between the flow field and parachute structure. This thesis presents the development of a CAD design and CFD methodology to the simulation of ram-air parachutes in steady-state conditions. Starting from a 2D rib drawing, methods were developed to approximate the 3D geometry and efficiently model the parachute as a rigid and impermeable body. The use of distortions was implemented on a 2D, pseudo-2D, and 3D model to enhance their behavior during a real flight. The SST turbulence model was chosen for the modeling of these designs because of its suitability to predict flow separation and reattachment from adverse pressure gradients. The high complexity of the 3D model is handled using appropriate boundary conditions and cleaning geometric tools within the CFD software. Visualization of the fluid flow parameters such as lift and drag coefficients at different angles of attack allow to evaluate aerodynamic performance at the specified flight conditions and provide clear trends for best model shapes. The computational results were compared to other experimental and numerical studies.
