research overview

  • Dr. Neogi's research is at the interface between the fields of materials physics and thermal sciences and focuses on controlling of vibrational energy transport in a wide variety of systems using analytical methods and numerical tools. Control of phonons, the quanta of lattice vibrations, will enable guided heat conduction in materials, improve thermoelectric energy conversion and stability of quantum states in atom-like defects. The CU Aerospace Nanoscale Transport Modeling (CUantam) Laboratory is also active in employing first principles methods to predict electronic transport properties of experimentally realizable systems. Additionally, the group is focused on developing methods to predict thermal and electronic properties of complex systems of sizes beyond the scope of first principles methods, by employing machine learning techniques, learning from first-principle results.

  • MCEN 6001 - Reacting Flows
    Primary Instructor - Spring 2019
    Provides an introduction to reacting flows and combustion. Covers chemical kinetics, including global and detailed mechanisms and the variable density flow equations are derived. Relevant non-dimensional parameters and limiting behaviors are discussed. The Rankine-Hugoniot relations are presented and various aspects of diffusion, kinetically dominated and balanced combustion are outlined. Flame structures are discussed, including laminar and turbulent flames, and the Burke-Schumann solution is outlined. The turbulent forms of the motion equations are derived, and the reactive scalar transport equation and mixture fraction variable are presented. The flamelet progress variable approach is outlined, including a comparison of steady and unsteady flamelet models. Specific topics in spray combustion, triple flames, solid-gas reactors and detonations are discussed. Same as ASEN 6001.
