Chapter 10 – Companion Computer Programs
Analysis of Turbulent Flows with Computer Programs, 2020Co-Authors: Tuncer CebeciAbstract:In this chapter several computer programs for calculating two-dimensional laminar and turbulent incompressible flows are described. First, computer programs and sample calculations based on integral methods are described; then a program based on the differential method, applicable to both laminar and turbulent flows for a given External Velocity Distribution and transition location is presented, along with sample calculations for an airfoil with the External Velocity Distribution obtained from a panel method. Computer programs for incompressible laminar and turbulent flows with heat transfer and for infinite-swept wing flows, respectively, are then discussed, followed by another differential method for two-dimensional incompressible turbulent flows with Cebeci-Smith and k-e models. The chapter concludes with programs and subroutines relevant to Problems and discussions in previous chapters.

Boundary-Layer Methods
Analysis of Low-Speed Unsteady Airfoil Flows, 2020Co-Authors: Tuncer Cebeci, Max F. Platzer, Hsun Chen, K. C. Chang, Jian P. ShaoAbstract:This chapter is concerned with the solution of the boundary-layer equations of subsection 2.4.3 for boundary conditions that include a priori specification of the External Velocity Distribution either from experimental data or from inviscid-flow theory (called the standard problem), a priori specification of an alternative boundary condition which may be a displacement thickness Distribution (called the inverse problem), or the determination of the freestream boundary condition by iteration between solutions of inviscid and boundary-layer equations (called an interaction problem).

Predicting Stall and Post-Stall Behavior of Airfoils at Low Mach Numbers
AIAA Journal, 1995Co-Authors: Tuncer Cebeci, Hamid Hefazi, Farzam Roknaldin, Lawrence W. CarrAbstract:An interactive boundary-layer method, together with the e"approach to the calculation of transition, is used to predict the stall and post-stall behavior of airfoils in incompressible and compressible flows at low freestream Mach numbers. Two separate inviscid methods—a panel method with compressibility corrections and a full potential method—are used to compute the External Velocity Distribution needed in the solution of the compressible boundary-layer equations. The turbulence model is based on the Cebeci-Smith algebraic eddy-viscosity formulation with improvements for strong pressure gradient effects. Comparison of calculated results with inviscid flow computed with a panel method indicate excellent agreement with experiment for a wide range of Reynolds numbers in incompressible flows. Comparison of calculated results obtained with inviscid flow computed with a full potential method also indicate excellent agreement with experiment for a wide range of angles of attack, including stall for compressible flows at low freestream Mach numbers. The study also shows that even though the compressibility corrections to the panel method are adequate at small-to-moderate angles of attack, they are not satisfactory at higher angles of attack, especially near stall.
