报告摘要：

This lecture gives rather biased discussions emphasizing the importance of “understanding” of phenomena. This lecture’s purpose is to inspire young researchers to taste the real charms of research by observing the process of development of mathematical models of vortex-induced vibration phenomena of cylinders for understanding their essential mechanism. Generally, research and studies in wind engineering are aimed at solving given problems caused by physical phenomena induced by winds. As such, they have direct and concrete aims such as observation of phenomena, prediction of phenomena, understanding of phenomena, and solution of problems. The last of these can be replaced by design practice. One of the important aims of research and studies is to “understand” phenomena. Simulation and prediction of phenomena can be done without understanding the phenomena. However, the discussions of this lecture focus on “understanding” of phenomena. It first discusses imperfect abilities of human beings in observation of phenomena and important aspects of research. Then, it emphasizes the close relation between understanding and mathematical models, and five conditions for a desirable mathematical model: simplicity; inclusion of all essential properties; possession of physical meanings; wide scope of application; and possibility of development.
