Analysis of Viscous Transonic Flow over Airfoil Sections
A full Navier-Stokes solver has been used t o model transonic flow over three airfoil sections. The method uses a two-dimensional, implicit, conservative finite difference scheme for solving the compressible Navier-Stokes equations. Results are presented as prescribed for the Viscous Transonic Airfoil Workshop to held at the AIAA 25th Aerospace Sciences Meeting. "Jones" airfoils have been inves...
متن کاملQuasi-Simultaneous Viscous-Inviscid Interaction for Transonic Airfoil Flow
Following Prandtl, a viscous-inviscid interaction (VII) method is presented, where the flow field is divided into a viscous shear layer and an inviscid outer region. Their coupling is performed with the quasi-simultaneous approach, making use of an appropriately chosen interaction law. Firstly, an engineering example of transonic airfoil flow is presented, in which the interaction law is based ...
متن کاملdirect numerical simulation of supersonic and transonic compressible viscous flow by kinetic energy preserving scheme
present paper investigates the numerical solution of two-dimensional unsteady compressible navier-stokes equations by a new scheme based on the finite volume method. kinetic energy preserving (kep) scheme is introduced for solving the supersonic and transonic external compressible flow field on very fine grids (with a number of cells of the order of the reynolds number) without artificial dissi...
متن کاملRadial Viscous Flow between Two Parallel Annular Plates
Deduce the velocity distribution of steady flow of an incompressible fluid of density ρ and viscosity η between two parallel, coaxial annular plates of inner radii r1, outer radii r2 and separation h when pressure difference ∆P is applied between the inner and outer radii. As an exact solution of the Navier-Stokes equation appears to be difficult, it suffices to give an approximate solution ass...
متن کاملTransonic Flow Calculations
In these lectures I shall attempt to survey some of the principal recent developments in computational aerodynamics. Prior to 1960 computational methods were hardly used in aerodynamic analysis, although they were already widely used for structural analysis. The NACA 6 series of airfoils had been developed during the forties, using hand computation to perform the Theodorsen method for conformal...
