PREFACE This book contains a collection of papers presented at the Parallel CFD 1995 Conference held on June 26-28, 1995 in Pasadena, California. The Parallel CFD Conference is international in scope and has doubled in participation since its inception in 1989. Past conferences have been held in France, Germany, Japan, and the United States. In order to keep track of current global developments in a fast growing field, the Parallel CFD Conference annually brings individuals together to discuss and report results on the utilization of parallel computing as a practical computational tool for solving complex fluid dynamic problems. The purpose of this volume is to disseminate results of research conducted during the past year. The content of the papers included in this volume suggest that there is considerable effort being made to utilize parallel computing to solve a variety of fluid dynamics problems in topics such as climate modeling, consultation, aerodynamics, and many others. The papers presented at the 1995 conference included subject areas such as novel parallel algorithms, parallel Euler and Navier-Stokes solvers, parallel Direct Simulation Monte Carlo method, parallel multigrid techniques, parallel flow visualization and grid generation, and parallel adaptive and irregular solvers. The applications of interest included the following: reacting flows, rarefied gas flows, multiphase flows, and turbulence; vehicle design, hypersonic reentry problems, and aerodynamic flows; challenges such as moving boundaries, interfaces, free surfaces and fluid-structure interactions; and parallel computing in aeronautics, astronautics, mechnical engineering, and environmental engineering. We would like to thank all of the sponsors of the 1995 conference whose su
