Data assimilation problems for 2d Eulerian rotating turbulent flows have been also developed by using both equations-based and data-driven tools, including linear methods based on principal orthogonal decomposition and non-linear ones, based on convolutional neural networks. Comparison against nudging is also systematically performed. Explorative studies of complex multi-component and multi-phase flows, using Lattice Boltzmann Techniques, and development of new algorithm to study nucleation with mesoscopic approaches are also under investigation. Among the most important impact for the society we cite the possibility to better assimilate data for numerical weather forecast, develop augmented reality approaches for bio-fluids and medicine, developing of optimal strategies for odor and contaminant sources in the presence of strong flow fluctuations. The overall objectives are to make a quantitative jump to data-driven approaches for fluid dynamics, offering open data suites to help the community for developing benchmarks and grand challenges,
(i) numerical algorithms for direct numerical simulations HPC applications of odor sources emissions in turbulent flows with mean wind.
(ii) developed Lattice Boltzmann Approaches for Nudging in Rayleigh Benard
(iii) Algorithm using Reinforcement Learning for single and multile Lagrangian probes in complex flows
(iv) algortihms using Generative Adversarial Networks (GAN) for Data Assimilation of geophysical flows
(v) algorithms using POD and EPOD to benchmark GAN approaches
(vi) Algorithms based on Lattice Boltzmann for multi-component micro and nano fluids
Main results:
(i) first application of Nudging to Rayleigh Benard at high turbulent intensity
(ii) first application of GAN to reconstruct fully developed turbulent rotating flows
(iii) first application of adversarial reinforcement learning to study prey-preadator dynamics at low Reynolds
(iv) development of theoretical definition of Tolmann length for nucleation problems at nano-scale using mesoscopic algorithms
(v) studyng of non-newtonian effects in complex emulsions
