At the graduate level, Dr. Echekki has taught Fluid Dynamics of Combustion I (MAE 504) and the follow up advanced combustion course, Fluid Dynamics of Combustion II (MAE 704). He also has taught the graduate Fluid Dynamics course, Foundations of Fluid Dynamics (MAE 550) and an introduction to Turbulence, Turbulence (MAE 776).

At the undergraduate level, he has taught Engineering Thermodynamics I and II (MAE 201 and MAE 302) and fluid Mechanics I (MAE 308). All of these classes are foundational. Drawing on personal experiences, he discusses new applications in combustion in the second thermodynamics course to give the students a greater appreciation of the challenges in the field and to encourage further reading.

Combustion plays an important role in the solution of many of the engineering problems that we face today. Graduate students who work with Dr. Echekki are also drawn to this area because of its breadth. The reliance of combustion on thermodynamics, heat transfer, and fluid mechanics means that the subject is never boring and provides a foundation from which the student can later branch out.

Outside of work, Dr. Echekki spends time with his family and friends.

Research Description

Dr. Echekki primary interests are in the modeling and simulation of turbulent combustion with emphasis on models that overcome the challenges of closure related to turbulence-chemistry interactions. At present, Dr. Echekki is pursuing the development of multi-scale models for turbulent combustion, the development of data-based closure strategies, including experimental data. Multi-scale models involve the hybrid coupling of coarse solution schemes, such as large-eddy simulation (LES), to fine-grained low-dimensional simulations embedded in the coarse solution to capture unresolved physics. Examples of such hybrid approaches include the LES-ODT approach, which couples LES to 1D solutions for multi-component transport and chemistry based on the one-dimensional turbulence (ODT) model. Data-based models exploit the growing availability of high-fidelity simulations and experiments to construct turbulent combustion closure models.
