Transonic 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...
متن کاملA Finite Volume Method for Transonic Potential Flow Calculations
It is proposed to solve the exact transonic potential flow equation on a mesh constructed from small volume elements, which can be conveniently packed around any reasonably smooth configuration. the calculation is performed on two sets of interlocking cells. The velocity and density are calculated in the primary cells, and a flux balance is then established in the secondary cells. The scheme is...
متن کاملUnsteady Flow Calculations with a Parallel Multiblock Moving Mesh Algorithm
A novel parallel dynamic moving mesh algorithm designed for multiblock parallel unsteady ow calculations using body- ttedgrids is presented.Themoving gridalgorithmwithin each block uses amethod of arc-length-based trans nite interpolation, which is performed independently on local processors where the blocks reside. A spring network approach is used to determine the motion of the corner poi...
متن کاملTRANSONIC FLOW CALCULATIONS USING TRIANGULAR FINITE ELEMENTS Richard
Princeton University, Princeton, NJ This paper desribes a technique for finding the numerical solution of the Full Potential equation for steady transonic flow about airfoils. The exterior but finite domain is discretized by breaking it up into triangles. Difference equations are formulated using variational principle and a formula for the derivative in an arbitrary polygon. The iterative schem...
متن کاملTransonic Potential Flow Calculations by Two Artificial Density Methods
A steady transonic flow over an airfoil is computed by solving the full potential equation discretized over a contour-fitting grid in full conservation form. Near shock waves, density is corrected to account for the rise in entropy in the region. A multigrid alternating direction method is used to drive the iteration. In supersonic flow regions, artificial dissipation is introduced by retarding...
