Description
Summary:This paper discusses an on-going research effort to develop a more computationally efficient scheme, for the direct simulation of wind flow around bluff bodies. Direct simulation as used in this study is based on providing a robust numerical solution to the 2-D primitive variable form of the Navier–Stokes equations. This approach to simulation of wind flow is increasingly becoming more attractive, especially, since very fast and low-cost computers are now readily available to most users. The objective of the present study is thus, to enhance the computational speed of an existing finite-difference-based wind simulation scheme already implemented by the authors. The resulting wind flow simulation software is designed for use in an engineering workstation environment, in which, the new coupled scheme offers more efficient and improved computational effort. The main thrust of this paper is a discussion of the mathematical modeling of the new coupled scheme, and finally a presentation of some preliminary results obtained from numerical experimentation.
