New Directions in Computational Fluid Dynamics

Computational Fluid Dynamics (CFD) deals with the solution of fluid­ dynamic equations on digital computers and the related use of digital computers in fluid-dynamic research. It is used for basic studies of fluid dynamics, for engineering design of complex flow configurations, for understanding and predicting the interactions of chemistry with fluid flow for combustion and propulsion, for basic and applied research into the nature and properties of turbulence, for interpreting and analyzing experi­ mental data, and for extrapolation into parameter regimes that are rela­ tively inaccessible or very costly to study experimentally. Recent successes in computational fluid dynamics are based on inno­ vative numerical algorithms that discretize the continuum equations offluid dynamics into a large but finite number of algebraic or ordinary differential equations. These equations are then solved using currently available, large­ memory, high-speed digital computers. A number of books, conference proceedings, and review articles have recently been written on this subject. Among them, CFD in aerodynamics is considered in National Academy of Sciences/National Research Council ( 1986), reactive flow in Oran & Boris (1987), fluid mechanics and heat transfer in Anderson et al. (1984), strongly shocked flows in Woodward & Colella (1984), and spectral methods for subsonic flows in Canuto et al. ( 1988). Books treating opti-
