This volume constitutes the Proceedings of the First International Conference on Computational Fluid Dynamics, held at the Kyoto Research Park, Kyoto, Japan on 10-14 July, 2000. The conference is the first one at which the International Conference on Numerical Methods in Fluid Dynamics (ICNMFD) and the International Symposium on Computational Fluid Dynamics (ISCFD) were merged. The purpose of the conference was to bring together scientists, mathe­ maticians, and engineers to review and share recent advances in mathematical and computational techniques for modeling fluid dynamics. The conference had the following format: Each day of the conference except Wednesday (July 12) started with a plenary session at which an invited lecture was delivered. During the rest of the day there were three sessions in parallel in which oral presentations were made. Poster presentations were also made on Monday, Tuesday and Thursday afternoons. A total of 205 abstracts were submitted from all over the world, and were evaluated by five paper selection committees chaired by J.J. Chattot (USA), KW. Morton (UK), M. Napolitano (Italy), K Srinivas (Austraria) and myself. Out of 136 papers accepted for oral presentations, 17 were withdrawn and out of 46 papers accepted for poster presentation, 14 were cancelled.
