Environmental & Climate Sciences Department Seminar

The talk will summarize Dr. Ladeinde's contributions to three research areas of his interest and expertise. One of these areas is theoretical and DNS studies of scalar and chemical species transport, mixing, and combustion in turbulent flows, for which his recent work on compressible turbulence in detonation will be presented. Dr. Ladeinde has also contributed significantly to the knowledge of supersonic combustion, which pertains to the propulsion of hypersonic vehicles, for which combustion takes place in an environment where the velocities of the reactants are in the high subsonic or supersonic regimes. A snapshot of Dr. Ladeinde's recent LES studies on the rotating detonation engines (RDE) will be summarized during the talk. The third research area of current interest to Dr. Ladeinde is two-phase flows in its various occurrences: condensation, boiling, and evaporation in heat transfer, as well as fuel primary and secondary breakup and eventual evaporation, mixing, and reaction with an oxidizer, in combustion. Both empirical and CFD-based techniques for two-phase flow studies have been undertaken by Dr. Ladeinde and these will be discussed briefly. The relevance of these backgrounds to climate studies, which can be found in theoretical, LES, and DNS analysis of atmospheric turbulence - with and without transported species or chemical reactions and phase-change – will be discussed.
