research overview

  • Dr. Evans' research interests are in the design, analysis, and implementation of numerical methods for fluid and structural mechanics and wave propagation. Dr. Evans is particularly interested in high-order methods which preserve important structure (geometry, balance laws, entropy inequalities, maximum principles, topological constraints) and account for multiscale behavior (such as turbulence) in a mathematically and physically consistent manner. In addition, Dr. Evans is actively involved in the development of integrated engineering design, analysis, and optimization technologies.

Teaching

courses taught

  • ASEN 3111 - Aerodynamics
    Primary Instructor - Fall 2019
    Develops the fundamental concepts of aerodynamics and provides a working knowledge for their application to the design of aircraft and launch vehicles operating at various speeds and altitudes, as well as the atmospheric forces on satellites. Offered fall only.
  • ASEN 5037 - Turbulent Flows
    Primary Instructor - Spring 2018
    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 5051 - Fluid Mechanics
    Primary Instructor - Fall 2018
    Highlights physical properties of gases and liquids; kinematics of flow fields; and equations describing viscous, heat-conducting Newtonian fluids. Emphasizes exact solutions and rational approximations for low and high speed dissipative flows, surface and internal waves, acoustics, stability, and potential flows.
  • ASEN 6519 - Special Topics
    Primary Instructor - Fall 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 7221 - Turbulence
    Primary Instructor - Spring 2018
    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.
