Biography

Dr. Alexey Volkov conducts fundamental research of complex physical phenomena in multiphase media that require multiscale theoretical models, advanced numerical methods and combined atomistic, mesoscopic, kinetic and continuum simulations. In particular, he studies how the accurate theoretical description of physical processes on nano- and microscales can be incorporated into coarse-grained robust computational models capable of prediction of macropsopic properties of multiphase media, which are of interest for engineers. The computational tools based on the multiscale models help to predict properties of nanomaterials, advance novel technologies of the material processing, and design various miniaturized devices. Such models are also necessary for understanding general physical phenomena observed on Earth and in the universe, e.g. processes that govern the evolution of planetary bodies and their atmospheres in the Solar system and extrasolar planets.

Dr. Alexey Volkov has published more than 70 book chapters, peer-reviewed journal papers and papers in the conference proceedings. His current research interests are:

  • Mechanics, thermal transfer and gas flows in carbon nanotube, nanofibrous and nanoporous materials.
  • Laser-material interaction, laser-induced phase transformations, laser ablation, laser plume expansion and laser processing of materials.
  • Planetary sciences: Dynamics of upper atmospheres, thermal escape, comets, Kuiper belt objects (KBOs) and exoplanets.
  • Development of mesoscopic computational models for advanced nanostructured materials and microscale processes, which bridge the gap between macroscopic continuum models and atomistic simulations.
  • Applications of the rarefied gas dynamics and direct simulation Monte Carlo (DSMC) method for simulations of various non-equilibrium gas flows.
  • Multiphase gas-solid particle and gas-liquid flows, heat and mass transfer with applications in aerospace engineering and material processing.
  • Computational fluid and gas dynamics including novel meshless computational methods for interfacial and multiphase flows.
  • High-performance parallel computing.

Dr. Volkov’s teaching interests focus on the general field of computational mechanics, including advanced engineering analysis, fluid and gas dynamics, rarefied gas dynamics and non-equilibrium gas flows, computational fluid mechanics, heat and mass transfer, numerical analysis, particle-based and meshless numerical methods, high-performance computing and programming.
