Title: Spatial and/or temporal growth of water waves in a wind-wave flume
Prof. Michael Stiassnie is seeking a suitable qualified researcher to undertake Post-Doctoral study to develop a theoretical model for the growth of water waves in a wind-wave flume, under his supervision.
About Technion:
For more than eight decades, the Technion-Israel Institute of Technology, which is located in Haifa, has been Israel’s primary technological university and the largest center of applied research. It is ranked among the leading technological universities in the world. The Department of Civil and Environmental Engineering has 60 senior faculty members active in research and education, and they currently supervise the education of ~900 undergraduate students, ~240 master degree students, ~85 doctor students, and ~10 post-doctoral researchers.
Project Abstract:
The importance of adequate description of interaction of wind with ocean waves cannot be overestimated, both on the global level of earth climate, and on a more local level of the necessity to predict the sea state for practical operation of off-shore and near-shore facilities. The goal of this study is to gain a better understanding of the dominant phenomena that determine the growth of waves under the effect of wind in a laboratory flume. This will enable us to offer better modeling of wind-wave growth rate. To attain this goal, it is crucial to realize that as water waves are affected by wind, the wind velocity profile in the vicinity of air-water interface is strongly affected by the waves.
Detailed measurements of the air and water flow field in a laboratory wind-wave flume and of the spatial and/or temporal evolution of the wave field will be carried out by a partner team, lead by Prof. Lev Shemer at the Tel-Aviv University. The experimental results will be compared with new computations based on the solution of the Orr-Sommerfeld equation for the experimentally determined air and water velocity profiles. Such a comparison will lead to critical assessment of the underlying model assumptions and to introduction of appropriate modifications. It is expected that an iterative experimental-theoretical process will lead to a better understanding of the physics of air-water flow interaction, in particular of the wind-wave growth mechanism, and as a result to a more accurate theoretical description of this process.
