Abstract
Over the next 20 years, Boeing will likely develop, manufacture, sell, and support many thousands of vehicles that fly. During this period, Boeing project aerodynamicists need access to tools that accurately predict and confirm vehicle flight characteristics. Thirty years ago, these tools consisted almost entirely of analytic approximation methods, wind tunnel tests, and flight tests.With the development of increasingly powerful computers, numerical simulations of various approximations to the Navier–Stokes equations have begun supplementing these tools. Collectively, these numerical simulation methods have become known as computational fluid dynamics (CFD). This chapter describes the algorithm issues and challenges associated with the development of reliable Navier–Stokes codes that can be used by a wide variety of project engineers who do not necessarily have a deep background in numerical methods.
