Dr. Samer Ali is an Associate Professor of Mechanical Engineering at JUNIA HEI (Lille, France) and researcher at the LGCgE (ULR 4515). His work lies at the intersection of heat transfer, computational fluid dynamics (CFD), and sustainable energy systems, organized around three complementary research axes. The first investigates self-oscillating flexible vortex generators as passive flow-control devices that enhance convective heat transfer and mixing through fluid–structure interactions. The second develops advanced CFD-based optimization tools—including adjoint, surrogate, and topology optimization methods—applied to heat exchangers, vortex-generator design, and renewable energy components. The third explores hybrid and renewable energy systems, integrating waste-heat recovery, thermoelectric conversion, and solar or geothermal resources into efficient low-carbon configurations such as PV/T-heat-pump and multi-drain recovery systems. His multidisciplinary approach bridges fundamental flow physics, numerical optimization, and applied energy engineering, aiming to design thermally efficient, cost-effective, and environmentally responsible technologies for next-generation energy systems.
