Our Research

Enabling volumetric modulation of the fluid dispersion, mixing, and heat transfer properties of engineering systems by implementing rigorously architected porous structures*.

*Conventionally, the fluid and heat transfer behavior of a system is only controlled by externally imposed boundary conditions (i.e. Reynold’s number of the incoming flow). However, materials permeable to flow can be engineered at the micro-scale to alter the fluid behavior and achieve desired macro-scale transport properties.

What we do.

We contribute scientifically rooted innovations that enable high-efficiency, low-emission, and robust energy management technologies by advancing the fundamental understanding and practical application of tailored porous structures in heat and fluid flow environments.

How we do it.

Using non-invasive diagnostics, multi-fidelity computational models, and topology optimization, our research group pursues a synergetic experimental and computational paradigm to:

    1. Conduct basic science for the fundamental understanding of the coupling between micro-scale geometry, material property, and macro-scale transport and flow features.

    2. Develop affordable predictive tools for gaining system-level insights and enable design optimization.

    3. Design, optimize and fabricate tailored structures using advanced additive manufacturing technologies.

Why we do it.

We aim to develop solutions to the global energy crisis and towards reducing carbon emissions, particularly in combustion, electrochemistry, and other complex flow systems.

Targeted applications include novel energy conversion and thermal management systems:

Thermal protection systems

Heat shields for atmospheric entry of space vehicles

Electrochemical cells

Gas diffusion electrodes for CO2 reduction

Advanced combustion technologies

Enabling reliable utilization of low-calorific biofuels

Our lab is located at 182 Grumman Hall on the Cornell campus in Ithaca, NY

Consisting of approximately 850 sq. ft. of laboratory space, the Sobhani Lab currently focuses on: ceramic additive manufacturing, experimentation and computation of combustion and other thermofluid flows, non-intrusive diagnostic methods including X-ray radiography and tomography.
