معرفی
Prof. Alexander Gelfgat is a faculty member at the School of Mechanical Engineering, part of the Faculty of Engineering at Tel Aviv University. His research focuses on hydrodynamic stability, bifurcations, flow control, and computational fluid dynamics (CFD), particularly in crystal growth, MHD, and high-performance computing contexts.
- Research Interests:
- Hydrodynamic stability and bifurcations
- Convection and rotating flows
- Shear layer dynamics
- Moving boundary tracking
- Crystal growth and melt flow
His work spans three-dimensional flow instabilities, with applications to Czochralski crystal growth, Dean flows, and two-phase stratified channels. Recent studies emphasize non-modal disturbances and quasi-two-dimensional flow projections for enhanced visualization.
Prof. Gelfgat has advised notable researchers including Yuri Feldman and Helena Vitoshkin. His publications address critical challenges in boundary layer instability, cross-flow wave propagation, and pressure-velocity coupled formulations for lid-driven flows in complex geometries.
