Computational Methods and Experimental Measurements: Proceedings of the 2nd International Conference, on Board the Liner, the Queen Elizabeth 2, New York to Southampton, June/July 1984

This book contains the edited proceedings of the 2nd Internat­ ional Conference on Computationa1 Methods and Experimental Meas­ urements held on board the QE2 liner from 27th June to 2nd Ju1y 1984. The meeting was sponsored by the International Society for Computationa1 Methods in Engineering and the Department of Civi1 Engineering, Southampton University and organized by the Computationa1 Mechanics Institute of Southampton, England. The QE2 provided an ideal environment for the international meeting and one that was equa11y convenient for the USA and European re­ searchers and offered a 10cation propitious to the interchange of ideas and c10se contact between participants. This book covers a wide range of different topics in Computat­ iona1 Methods and Experimental Measurements with the main empha­ sis on the re1ationships between experimental and ana1ytica1 5- utions. The first section deals with fluid dynamics problems and a 1arge number of app1ications. Section 2 considers geophysica1 fluid dynamics and describes some atmospheric models and their re1ated problems. Water resources are dealt with in Section 3 which describes some app1ications of porous media f10w and sur­ face water mode11ing. Wave interaction problems are described in Section 4 and Section 5 considers some important heat transfer app1ications. Other sections - 6 & 7 - study problems re1ated to stress analysis and structura1 app1ications. Vibration pro­ blems are becoming of fundamental importance in engineering and part of the Conference Proceedings - Section 8 - are dedicated to the study of experimental and computational models.
