Numerical Solution of Incompressible Turbulent Flow over Airfoils (Harwood A. Hegna) Faculty Dissertations (1981)

Numerical solutions are obtained for two-dimensional incompressible turbulent viscous flow over airfoils of arbitrary geometry. An algebraic eddy viscosity turbulence model based on Prandtl's mixing length theory is modified for separated adverse pressure gradient flows. ...

Numerical Prediction of Dynamic Forces on Arbitrarily Pitched Airfoils in Turbulent Flow (Harwood A. Hegna) AIAA Journal (1983)

Numerical solutions for an NACA 0012 airfoil undergoing various pitching motions are compared with both static and new dynamic experimental data. The unsteady incompressible Reynolds-average Navier-Stokes equations for a rotating coordinate system are used. A ...

Numerical Solution of Incompressible Turbulent Flow over Airfoils Near Stall (Harwood A. Hegna) AIAA Journal (1982)

Numerical solutions are obtained for two-dimensional incompressible turbulent viscous flow over airfoils of arbitrary geometry. A body-fitted coordinate system is numerically transformed to a rectangular grid in the computational plane. The unsteady Reynolds-averaged Navier-Stokes equations ...

Rarefied Gas Flow Through a Slit (Harwood A. Hegna) Physics of Fluids (1972)

The transition from near free molecule flow to slow viscous continuum flow through a slit has been studied experimentally. The measurements have been compared with the results of a theoretical analysis of the expected flow ...
