Book Description
The finite element technique is applied to steady incompressible, subsonic and transonic flow with the end objective being the analysis of unsteady transonic flow. A triangular cubic element is used and the Galerkin method of weighted residuals is adapted to control the error. The formulation is based on the small disturbance but nonlinear transonic equation for inviscid compressible flow. Full potential formulations with small disturbance assumptions are also investigated. The governing equations are cast into the Poisson type for which finite element analogs are constructed, and the solution is then obtained by iterative procedures. Boundary conditions involving the normal derivative of the unknown functions are conveniently cast into boundary integrals and added to the right-hand side of the equations. In the case where more than two unknown parameters are related, such as those along the branch cut, Lagrangian multipliers are used to introduce these constraints and a special equation solver is developed for these computations. Techniques are developed for analyzing lifting flow under free flight conditions with general provisions for surface tangency, wake and far field boundary conditions. This generality allows for computation of combinations of internal axd external flow (as an airfoil in a wind tunnel), as well as free flight, about arbitrary geometry. Unsteady transonic flow calculations are also presented for a NACA 64 A006 with an oscillating 25% chord control surface.

Book Description
We are delighted to present this book which contains the Proceedings of the Fifth International Conference on Computational Fluid Dynamics (ICCFD5), held in Seoul, Korea from July 7 through 11, 2008. The ICCFD series has established itself as the leading international conference series for scientists, mathematicians, and engineers specialized in the computation of fluid flow. In ICCFD5, 5 Invited Lectures and 3 Keynote Lectures were delivered by renowned researchers in the areas of innovative modeling of flow physics, innovative algorithm development for flow simulation, optimization and control, and advanced multidisciplinary - plications. There were a total of 198 contributed abstracts submitted from 25 countries. The executive committee consisting of C. H. Bruneau (France), J. J. Chattot (USA), D. Kwak (USA), N. Satofuka (Japan), and myself, was responsible for selection of papers. Each of the members had a separate subcommittee to carry out the evaluation. As a result of this careful peer review process, 138 papers were accepted for oral presentation and 28 for poster presentation. Among them, 5 (3 oral and 2 poster presentation) papers were withdrawn and 10 (4 oral and 6 poster presentation) papers were not presented. The conference was attended by 201 delegates from 23 countries. The technical aspects of the conference were highly beneficial and informative, while the non-technical aspects were fully enjoyable and memorable. In this book, 3 invited lectures and 1 keynote lecture appear first. Then 99 c- tributed papers are grouped under 21 subject titles which are in alphabetical order.
