The trimaran is a hull form that has potential application for high-speed sealift vessels. This hull form has less drag, larger deck area, and greater stability than a monohull designed for the same mission. However, much is unknown about the hydrodynamic characteristics of multiple hulls. The objective of this study was to explore innovative techniques for qualitatively visualizing flow that could provide insight to aid designers. The areas of concentration were flow on the surface of the hulls and throughout the fluid in the vicinity of the hulls, pressures on the hulls, and wakes between the hulls. The requirements were that the techniques must be safe, affordable, compatible with the model basins at the Naval Surface Warfare Center Carderock Division, and not interfere with other testing. These techniques would also be used to validate predictions made by Computational Fluid Dynamics software. After an analysis of the effectiveness and comparative cost of several methods, it was concluded that the best technique for visualizing the flow on the surface of the hulls is boiled linseed oil mixed with artist's paint. Particle Image Velocimetry is the recommended method for visualizing flow around the hulls. For assessing the pressures on the hulls and the wakes between the hulls, shear and pressure sensitive films from Innovative Scientific Solutions, Inc. appeared the most promising, although more development is still required.

Throughout history, flow visualization has been an important tool in fluid dynamics research. It has been used extensively in the fields of engineering, physics, medical science, meteorology, oceanography and sport aerodynamics, to name just a few. The importance of flow visualization led Professor F N M Brown (1971) of the University of Notre-Dame to comment, ?? A man is not a dog to smell out each individual track, he is a man to see, and seeing, to analyze?? This statement encapsulates the importance of first visualizing the flow before proceeding with detailed measurement and mathematical modeling. In addition, there is a great deal of esthetic pleasure to be gained from seeing the results of flow visualization. This aspect of flow visualization reaches out to the general public: we are all familiar with the aspect of clouds in the sky, the trail of cigarette smoke, and the swirling patterns to be seen in rivers and seas.Unlike previous publications which concentrated mainly on the theoretical aspect of flow visualization, this book focuses on the techniques required to perform high quality flow visualization. It is aimed primarily at the practitioner of flow visualization studies. Obtaining good flow visualization results is, in many ways, more an art than a science, and experience plays a deciding role. Hence each chapter of this invaluable volume has been written by an expert in a particular technique.

With contributions from some of the world's leading experts, the second edition of this classic reference compiles all major techniques of flow visualization and demonstrates their applications in all fields of science and technology. A new chapter has been added that covers flow visualization applications in large wide tunnels for airplane and automobile testing. Several important examples of applications are included. A second new chapter details the use of infrared (IR) cameras for detecting and observing the boundary layer transition in industrial wind tunnels and flight testing of commercial transport airplanes. A final new chapter has been added on multiphase flow and pulsed-light velocimetry.

Over the last decade, flow visualization has advanced in step with the progress in laser and computer technologies. The scope of the International Symposium on Flow Visualiza- tion will be broader than ever, covering the range of infor- mation generally thought of as nonvisual and reflecting the inclusion of computer - aided methodologies. The Sixth In- ternational Symposium on Flow Visualization aims to attract the participation of experts and users of flow viualizing techniques on furthering an advanced philosophy for the de- velopment of the methods and their applications.

Progress in fluid mechanics depends heavily on the availability of good experimental data which can inspire new ideas and concepts but which are also necessary to check and validate theories and numerical calculations. With the advent of new recording and image analysis techniques new and promising experimental methods in fluid flows have presented themselves which are rather newly developed techniques such as particle tracking velocimetry (PTV), particle image velocimetry (PIV) and laser fluorescene (LIF). This volume presents state-of-the-art research on these techniques and their application to fluid flow. Selected papers from the EUROMECH conference on Image Analysis are published in this volume.
