معرفی
Alexei Poludnenko is an Associate Professor at the University of Connecticut, specializing in combustion physics, detonation dynamics, and turbulent flows. His research focuses on numerical simulations of high-speed reacting flows, including spray detonations, hydrogen/hydrocarbon combustion, and astrophysical phenomena like Type Ia supernovae. He employs advanced methods such as Large Eddy Simulations (LES), Direct Numerical Simulations (DNS), and BLASTNet frameworks to study turbulence-chemistry interactions and detonation initiation mechanisms.
His work bridges terrestrial combustion systems and astrophysical scenarios, contributing to understanding flame acceleration, detonation cell structure, and turbulence-driven deflagration-to-detonation transitions. Key topics include shock-droplet interactions, multiphase detonations, and the role of compressibility in fast flames. Poludnenko’s research has implications for energy systems, propulsion, and fundamental combustion science.
Recent studies emphasize high-Reynolds number turbulence, phase equilibrium effects under high pressure, and the validation of reduced chemical kinetic models. His computational approaches address challenges in capturing multi-scale phenomena and improving predictive accuracy in complex reactive flows.
