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.

    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 5037.
  • ASEN 5051 - Fundamentals of Fluid Dynamics
    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. Recommended prerequisite: ASEN 3111 or ASEN 3711 (minimum grade B) or an equivalent course.
