A new model problem for static aeroelasticity is introduced and used to illustrate several alternative approaches for formulating multidisciplinary design optimization problems. The alternatives are distinguished by the kind of analysis problem feasi

This paper is about multidisciplinary (design) optimization, or MDO, the coupling of two or more analysis disciplines with numerical optimization.The paper has three goals. First, it is an expository introduction to MDO aimed at those who do research

The objective of this paper is to compare three optimization-based methods for solving aerodynamic design problems. We use the Euler equations for one-dimensional duct flow as a model problem. The optimization methods are (i) the black-box method wit

In industry today, the design process relies heavily on engineers-in-the-loop, making it is difficult to handle a sufficient number of design variables to optimize a complex product. Additionally, engineering disciplines are usually worked sequential

The study of the behavior of computational solutions of Burgers' equation at large mesh Reynolds numbers ReΔx is extended to a one-dimensional steady-state model gasdynamic system with downstream extrapolation conditions. The oscillations generally

In this paper we examine the mathematical structure of a model for three-phase, incompressible flow in a porous medium. We show that, in the absence of diffusive forces, the system of conservation laws describing the flow is not necessarily hyperboli

In this paper we develop an unsplit, higher order Godunov method for scalar conservation laws in two dimensions. The method represents an extension, for the special case being considered, of methods developed by Colella and by Van Leer. In our method

Explosion dynamics problems involve the propagation and interaction of shocks and contact discontinuities, usually in several space dimensions. Since standard finite difference methods which smear these discontinuities do not give sufficiently accura

The steady-state Burgers' equation uux = (I /Re) uxx (0 ⩽ x ⩽ 1) with boundary values u(0) = 0 and u(1) = -1 is employed as a model equation for fluid dynamics. It is shown how different conservative discretizations of the nonlinear term uux gove

Potempa, in his 1982 Ph.D dissertation, introduced a new numerical method for solving the equations describing multi-component single-phase flow in a porous medium. Potempa’s method has several desirable features including a substantial reduction o
