Biography
Tanaka Mitsuhiro is currently working in Gifu University, Japan. His research work is on henomena in fluids theoretically and numerically. The central theme of his research is the WAVE TURBULENCE (WT). WT is a field of waves where vast number of wave trains with different frequencies and directions of propagation coexist in space and time, interacting and exchanging energy with each other. The most familiar example of WT would be the ocean wave field, but it can also be observed in many different fields, such as in the atmosphere, plasmas, oscillating metal plates, etc. I am now especially interested in WT in a two-layer fluid system in which a lighter fluid lies on top of a heavier fluid. Such systems can be widely observed at the estuaries, upper oceans, etc. Two types of wave motion are possible in a two-layer system, i.e. surface wave and the interfacial wave. Our numerical simulation indicates that, due to a kind of nonlinear resonance between these waves, the energy spectrum of the surface waves evolves much more rapidly than in the case where there is no density interface.
