Multifractal Analysis and Simulation of Energy Fluctuations
Résumé
One of the key thematic areas for the development of future research in wind energy is turbulence. To better understand this topic requires the development of new numerical methods and measuring techniques capable of reaching micro scale effects. My PhD thesis will focus on advanced characterisation of micro-scale wind turbulence with respect to non-Gaussian heavy tailed statistics and short term extreme events (gusts) on the scales of 1 to 1000m and/or 1 to 100sec. Based on experimental data, multifractal wind field models with high frequency turbulent dynamics will be developed. Such models are promising candidates for providing initial flow conditions for turbulent dynamic computational fluid dynamics calculations. A combination of multifractals with other more classical models can open new perspectives for many industrial applications.
