Research

research overview

  • Dr. Hamlington's research is focused on understanding and modeling turbulent flows in both engineering and geophysical problems. His engineering research is focused on unsteady, boundary layer, and chemically reacting turbulent flows. The primary emphasis is on using theoretical analyses and data from large eddy or direct numerical simulations to understand fundamental turbulence physics in these flows. The longer-term objective is to use insights from these studies in the development of physically accurate models for large-scale simulations of realistic problems. Dr. Hamlington’s research on geophysical turbulence is currently focused on characterizing turbulent processes in the oceanic mixed layer. Ultimately, these studies may lead to more accurate parameterizations of subgrid-scale processes for larger-scale climate and weather simulations. Dr. Hamlington has also studied wind and ocean renewable energy technologies, as well as wildland fires.

  • ASEN 5037 - Turbulent Flows
    Primary Instructor - Spring 2019
    Studies turbulent closure methods and computational procedures used to solve practical turbulent flows. Emphasizes multi-equation models used with time-averaged equations to calculate free-turbulent shear-flows and turbulent boundary layers. Employs spectral methods in direct and large-eddy simulation of turbulence. Recommended prerequisite: ASEN 5051 or equivalent or instructor consent required. Formerly ASEN 6037.
  • ASEN 6519 - Special Topics
    Primary Instructor - Spring 2018
    Reflects upon specialized aspects of aerospace engineering sciences. Course content is indicated in the online Schedule Planner. May be repeated up to 9 total credit hours. Recommended prerequisite: varies.
  • MCEN 3021 - Fluid Mechanics
    Primary Instructor - Fall 2019
    Examines fundamentals of fluid flow with application to engineering problems. Topics covered include fluid statics and kinematics, Bernoulli equations, laminar and turbulent viscous boundary layers, laminar and turbulent pipe flow, and conservation equations for mass, momentum and energy. Same as CHEN 3200 and CVEN 3313.
  • MCEN 6001 - Reacting Flows
    Primary Instructor - Spring 2018
    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.
  • MCEN 7221 - Turbulence
    Primary Instructor - Spring 2019
    Hydrodynamic stability theory, equations for turbulent flows, free shear flows and boundary layers, homogeneous and isotropic turbulence, overview of turbulent combustion, reaction kinetics, energy equation, Favre averaging, Pdfs, premixed and nonpremixed flame modeling, and recent developments.
