About

Petr Nikrityuk studied mechanical engineering at the Moscow Aviation Institute-MAI (State University of Aerospace Technologies, Russia) , where he obtained his Mech. Eng. Diploma and Ph.D. Degree on the topic of mathematical modelling of thermal processes. He holds a Habilitation Degree from TU Bergakademie Freiberg (Freiberg University of Mining and Technology, Germany) on the topic of computational thermo-fluid dynamics in material science and engineering.

In 2001 he relocated from Russia to Germany, joining AEA Technology GmbH as a software development engineer in the field of computational fluid dynamics. After a year he took a postdoctoral fellow position at the Institute for Aerospace Engineering, Dresden University of Technology (Germany). Before taking his current position at the University of Alberta, Petr Nikrityuk was the head of the research group 'Interphase Phenomena' within the Center for Innovation Competence VIRTUHCON (Virtual High Temperature Conversion) at the TU Bergakademie Freiberg in the Department of Energy Process Engineering and Chemical Engineering. Petr Nikrityuk is a member of the American Society of Mechanical Engineers and German Association of University Professors and Lecturers.

Research

• Numerical modelling and simulation of particulate flows taking into account the heat and mass transfer between particles and fluid (CFD+DEM): development of subgrid models for Euler-Lagrange modellingchemically reacting particles.
• CFD-based simulations of processes related to heat- and energy-storage systems and energy-conversion devices (fixed bed systems).
• Macroscale and microscale numerical modelling of phase change phenomena under the influence of convection: binary metal alloys and heat storage materials, the influence of turbulence on the heat and mass transfer during phase change, interface tracking algorithms.
• Benchmarking and experimental validation of numerical models referring to immersed boundary methods
