Computational fluid dynamics — A personal view
Abstract
This paper provides a personal view of computational fluid dynamics. The main theme is divided into two categories — one dealing with algorithms and engineering applications and the other with scientific investigations. The former category may be termed computational aerodynamics with the objective of providing reliable aerodynamic or engineering predictions. The latter category is essentially basic research where the algorithmic tools are used to unravel and elucidate fluid dynamic phenomena hard to obtain in a laboratory. While dealing with the algorithms, only the underlying principles are discussed and the engineering applications are omitted. A personal critique of the numerical solution techniques for both compressible and incompressible flows is included. The discussion on scientific investigations deals in particular with transition and turbulence. In conclusion, some challenges to computational fluid dynamics are mentioned, the grand challenge being turbulence and reacting flows.
