What the grant funds

The Transport Phenomena (TP) program supports fundamental research to understand, model, and control the transport of mass, momentum, energy, and species across multiple scales. Innovative TP research supports advances in artificial intelligence; manufacturing; biotechnology; microelectronics; energy generation, extraction, and utilization; nuclear energy; quantum science and engineering; and other national priorities. TP projects involve experiments, theory, and/or computational modeling. They aim to improve understanding and to create novel analytical techniques. While projects focus on fundamental principles, they also have a clear vision of how research outcomes will benefit applications in engineering. TP supports research on the dynamics of single- and multiphase systems. Special interests include flow separation, transition to turbulence, drag reduction, cavitation, instabilities, and reactive flows. The program encourages research on the connection between dynamics at the microscale and material and flow properties at the macroscale. Fluids of interest include liquids, gases, suspensions, emulsions, granular materials, active fluids, biological fluids, colloids, aerosols, bubbles and drops, and fluids with surfactants. TP supports research on physicochemical phenomena at the interfaces between fluids and between fluids and solids. These phenomena include adsorption and desorption of nanoparticles and surfactants; bulk and interfacial rheology; wetting and capillarity phenomena; electrokinetics; flow in porous media; and directed and self-assembly of particles. TP supports research on thermodynamics and thermal transport involving conduction, diffusion, convection, phase transition, and radiation. Research may be across scales, in complex structures and at interfaces, in microelectronic devices, and in biological systems. Projects involving phonon transport and quantum thermal phenomena are welcome. TP encourages proposals focused on combustion of gas, liquid and solid fuels. Combustion topics of interest include chemical kinetic modeling, turbulence-chemistry interactions, detonations, plasma assisted reacting flows, sustainable fuels, mechanisms for pollutant control, and in-situ diagnostic methods. The program also supports research on wildland fire behavior that aims to prevent wildfire spread, inhibit its growth, and/or predict and mitigate fires at the wildland-urban interface.
