Research Activity
My research
work has been dealing with mathematical models and numerical methods for
numerical simulation aimed at problem solving in fluid
dynamics, material science, cultural heritage, planetology and environmental sciences.
Mathematical Models approached are listed:
- Navier-Stokes
equations for unsteady, incompressible, non-isothermal fluids (Direct Numerical
Simulation, Large Eddy Simulation, stability analysis and dynamical systems)
- incompressible non-Newtonian
fluid models (power law, differential type, GlenŐs law)
- liquid/solid phase transition models with convection and
deformation (artificial crystal growth, icy satellites of the solar system, subglacial lakes in polar regions)
- convection/diffusion equations for aqueous solutions with ionic
chemical species
- bio-fluid dynamics for the plankton ecosystem (natural
surfactant effects)
- rock-glacier
flow model based on granular material theory.
Numerical
Methodologies adopted are
the following:
- finite differences and finite volumes methods
- spectral and B-spline polynomial approximation methods
- domain decomposition technique
- front-fixing and front-tracking technique for moving
boundary problems
- regular and singular perturbation methods
