EISSN:1528-901X|ISSN:0098-2202|Disc:The Journal of Fluids Engineering disseminates technical information in fluid mechanics of interest to researchers and designers in mechanical engineering, and other engineering disciplines. The majority of papers present original analytical, numerical or experimental results and physical interpretation of lasting scientific value. Other papers are devoted to the review of recent contributions to a topic, or the description of the methodology, and/or the physical significance of an area that has recently matured. In addition, contributions to the Journal emphasize investigative techniques, analytical methods, computational fluid mechanics, and experimental methods such as Laser-Doppler-Velocimetry, hot film and hot wire anemometry, Particle-Imager-Velocimetry, and other innovative advances as they appear|Priority:12|Publisher:American Society of Mechanical Engineers|
