The research within Reactive Flow Modeling Laboratory at KAUST is focused on addressing both fundamental and applied challenges in simulating complex reactive flow problems.

Our research efforts concentrate on both the development of accurate and computationally affordable algorithms, as well as on the application of existing algorithms to challenging reactive flow problems and configurations.

Current Research

We perform large scale Direct Numerical Simulations of canonical, laboratory-scale, lean methane/air turbulent premixed flames at 4 atm. The goal of the project is to investigate the effect of the Reynolds number of the flow on the statistics of the flame and flow field, including overall burning rates, surface densities, and local flame propagation characteristics.​
Electric fields have been shown to affect flame behavior and combustion properties by acting upon the charged particles produced naturally in flames. Among the positive effects are improvement of stabilization characteristics and reduction of pollutant emissions. In our group, we are developing models to characterize the ion and electron distribution in flames and to predict flame behavior under electric fields.
​The formation of particles from supersaturated vapor is a fundamental process in aerosol-laden flows, both in nature and in technological applications. In our group we investigate the coupling between the spatially inhomogeneous mixing field and the aerosol microphysical processes. We carry out complementary experimental and numerical research activities.​
​Soot emissions are an undesirable by-product of rich combustion in technical combustion devices. Our group uses direct numerical simulation (DNS) understand and mitigate soot formation in turbulent flames.
Tribrachial flames play a role in the stabilization and dynamics of laminar and turbulent flames and their propagation is relevant to the partially premixed combustion regime. We conduct detailed simulation of tribrachial flames of complex hydrocarbon fuels with state-of-the-art methods for reactive flows in the low Mach number limit.
​Turbulent flow and mixing are widespread in nature and in technical applications. In our group, these flows are investigated via direct numerical simulation (DNS), solving over the whole set of time and length scales that characterize the physical processes.​
