Research Profile

Inspired by the intensive and extensive interest on basic theoretical research, I have been working on interdisciplinary research between turbulence, hydrodynamics and mathematics and nonlinear dynamics. Some fundamental results had been obtained concerning Lagrangian turbulence, helicity analysis and classical differential geometry, and hierarchical structure model of turbulence. Recently, some important advances have been made on the generalization of She-Leveque hierarchical structure model of turbulence, the phenomenology of probability density functions of multi-scale fluctuations of stochastic fields, the mathematical theory of scaling laws, the invariants of fluid Euler equation, and some new mathematical physics properties on the decomposition of three-dimensional vector fields.
