Earl Peter N. Duque  

Dr. Duque joined NAU in August 2000 after working as a research scientist for the Rotorcraft Advanced Computational Methods Group at NASA Ames Research Center. He teaches courses in the thermal sciences including Computational Fluid Dynamics, Heat Transfer and Renewable Energy. His current research consists of the development and application of Navier-Stokes flow solvers designed to predict the unsteady aerodynamics of wind turbines, bluff bodies and rotorcraft.
