Transonic Navier-Stokes Computations for an Oscillating Wing Using Zonal Grids Neal M. Chaderjian* and Guru P. Guruswamyt NASA Ames Research Center, Moffett Field, California Modern jet transports and maneuvering tactical fighters operating in the transonic regime often give rise to. Abstract. An Euler/Navier-Stokes zonal scheme is developed to numerically simulate the two-dimensional flow over a blunt leading-edge plate. The computational domain has been divided into inner and outer regions where the Navier-Stokes and Euler equations are used, by: 2. Flores J, Holst T, Kaynak U, Gunky K, Thomas S.

This article reports the results of unsteady Navier-Stokes simulations of transonic flows over a rigid arrow-wing body configuration with oscillating control surfaces. Computations have been made with and without control surface deflections. Computed pressures and integrated force coefficients have been compared with the wind-tunnel experiment. A finite-difference Navier-Stokes code is used in order to study the linearity of aerodynamic loads with respect to the dynamic angle of attack in threedimensional transonic flow. Navier-Stokes/Euler with Slip The new theory of flight is evidenced by the fact that the incompressible Navier-Stokes equations with slip boundary conditions are computable using less than a million mesh points without resolving thin boundary layers in DFS as Direct Finite Element Simulation, and that the computations agree with experiments.

PY - /12/ Y1 - /12/ N2 - The flutter boundary of the 3D AGARD Wing is calculated by using an efficient upwind scheme, Zha CUSP2, in moving grid by: 5. wing performances within a reasonable time, the three-dimensional Navier-Stokes equations must be solved because flows around a wing involve significant viscous effects, such as potential boundary-layer separations and shock wave/boundary layer interactions in the transonic Size: KB. A wing is a type of fin that produces lift, while moving through air or some other such, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils.A wing's aerodynamic efficiency is expressed as its lift-to-drag lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total . information obtained by solution of an adjoint problem, was ﬁrst applied to transonic ﬂow by Jameson , . He formulated the method for inviscid compressible ﬂows with shocks governed by both the potential equation and the Euler equations , , . With this approach, the cost of a design cycle is independent.
