Book Description
The fact that energy resources are not unlimited has lead the way for aerodynamic analysis for drag reduction. Innovative ideas, better visualization, reduced time in the design process, and cost effective "computational testing" is all put together is the use of computational fluid dynamics. In the present study, the analysis of the complex flow structure around a bluff body is presented. The importance and advantages of the numerical simulations are discussed. The quality of the mesh is of great importance and the types of grid generation schemes are presented here. The shape of the rear of the body has a marked influence on the body drag. The importance of the back slant angle and its effect on the flow structure and in turn, its effect on the drag force of the body is presented. The importance of computational fluid dynamics in the field of racing applications whereby cars in draft or cars in a cross flow that cannot be performed in the wind tunnel are presented and discussed. The accuracy of the computational calculations is validated by comparison with that of the experimental results. The computational results are in good accordance with the experimental results.
Turbulence and Molecular Processes in Combustion
Author: T. TakenoPublisher: Elsevier
ISBN: 0444598898
Category : Science
Languages : en
Pages : 462
Book Description
An understanding of the intricacies in the turbulent combustion process may be a key to solving many of the current energy and environmental problems. The essential nature of turbulent combustion can be derived from the interaction between stochastic flow fluctuations and deterministic molecular processes, such as chemical reaction and transport processes. Undoubtedly, this is one of the most challenging fields of engineering science today, requiring as it does the interaction of scientists and engineers in the respective fields of chemical kinetics and fluid mechanics. The 28 papers in this volume review recent advances in these two disciplines providing new insights into the fundamental processes, addressing a great deal of recent progress. This progress ranges from descriptions of elementary chemical kinetics, to working those descriptions into combustion calculations with large numbers of elementary steps, to improved understanding of turbulent reacting flows and advances in simulations of turbulent combustion. The contributions will inspire further research on many fronts, advancing the understanding of combustion processes, as well as fostering a growing interdisciplinary cooperation.

Engineering Turbulence Modelling and Experiments - 3
Author: G. BergelesPublisher: Newnes
ISBN: 0444600132
Category : Technology & Engineering
Languages : en
Pages : 932
Book Description
This book presents and discussses new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. At present, turbulence is one of the key issues in tackling engineering flow problems. Powerful computers and numerical methods are now available for solving the flow equations, but the simulation of turbulence effects which are nearly always important in practice, is still in an unsatisfactory state and introduces considerable uncertainities in the accuracy of CFD calculations. These and other aspects of turbulence modelling and measurements are dealt with in detail by experts in the field. The resulting book is an up-to-date review of the most recent research in this exciting area.

Author: J. M. SolomonPublisher:
ISBN:
Category : Aerodynamics, Hypersonic
Languages : en
Pages : 236
Book Description
A comprehensive computational procedure is presented for predicting the supersonic region of the flow field on advanced reentry vehicle shapes in steady flight at pitch and yaw. The procedure utilizes explicit second order accurate finite difference methods applied to the conservation law form of the steady inviscid flow equations. Improved numerical methods are used at the body surface and the bow shock wave. Provisions for treating body geometries with discontinuous slopes are also included. Either perfect gas or real gas equilibrium thermodynamic properties can be used. The computational procedure is implemented as a FORTRAN computer code which provides a practicable representation of the inviscid flow field and the resulting aerodynamic force and moment on the vehicle. In this report (Vol. I) the analytical and numerical development of the procedure is presented and the associated computer code is described. A comparison report (Vol. II User's Manual) contains detailed instructions for operating the code and interpreting the output results. (Author).
