Description
This postdoctoral research opportunity at the Naval Research Laboratory (NRL) focuses on the numerical simulation of turbulent flows, investigating mechanisms such as vorticity generation, turbulent dynamics, and transport phenomena. The program emphasizes nonequilibrium turbulence in both reacting and nonreacting flows, utilizing advanced computational methods including Direct Numerical Simulation (DNS) and Large-Eddy Simulation (LES) of hydrogen-air and methane-air combustion systems.
Additional research areas include multidimensional computational studies of the transition to turbulence and aeroacoustics in unstable shear layers and bounded flows. The work explores entrainment and mixing processes, coherent structure development, and the effects of density differences and compressibility in gas mixtures.
Physical systems of interest span turbulent jets and wakes, intense turbulence in channel flows with flames and detonations, swirling and free-surface flows, atmospheric turbulence, combustors, hot channels generated by laser and electric discharges from particle beams, and astrophysical flows.
