Scope of Researches
1.Nonlinear acoustic problems such as generation of “acoustic soliton,” suppression of shocks, resonant excitation of unshocked high-amplitude oscillations in a tube, thermoacoustic waves and oscillations in tubes and resonators, in view of applications to acoustic problems associated with traveling of high-speed trains, novel technologies of acoustic compressors and acoustic heat engines,
2.Nonlinear phenomena involving liquid sheets and drops such as capillary waves, Marangoni effects for surface tension due to variations of temperature and concentration, break-up of sheets and formation of drops, in view of applications to micro- and nano-technologies, and bio- medical problems,
3.Nonlinear waves and oscillations in fluid-structure systems such as localization and delocalization in a spatially periodic structures like articulated beams or panels traveling in a fluid-filled tube or floating on water, chaotic oscillations of a beam in a fluid-filled tube, in view of applications to high-speed trains traveling in a tunnel, and large-scaled structures like “Megafloat.”
