Computational Methods for Aerodynamic Design (Inverse) and Optimization.

摘要

Computational Fluid Dynamics (CFD) plays an increasingly important role in the aerodynamic design of flight vehicles. The main reasons for this are the rapid developments in computer hardware and solution algorithms in combination with the increasing requirements (and potential) for improving aerodynamic quality and reducing design cycle time and cost. This meeting focused on those CFD-based methods which address the problem of design for given aerodynamic characteristics in a direct sense. Examples are 'inverse' methods which provide the detailed geometry required to generate a given pressure distribution and methods using numerical optimization techniques to obtain the geometry that minimizes, subject to constraints, a given aerodynamic objective function such as drag, load distribution, etc. This volume consists of 23 papers: 3 invited/survey papers; Inverse methods -- Airfoils and wings (5 papers) and Turbomachinery (6 papers; and Numerical optimization techniques (9 papers). These proceedings also contain the Round Table Discussion conducted at the conclusion of the meeting. Keywords: Airfoils/computer-aided design symposia; Aerodynamic characteristics/optimization; Transonic airfoils; Navier stokes equations; Turbine blades; Lifting surfaces; Compressors/turbines; Turbomachinery intakes/ducts; Numerical analysis.
