using adaptive meshing for solving the transonic flow around airfoils
numerical analyses have shown that successful flow simulations and the accuracy of solution noticeably depend on the number of nodes used in computational meshing. a suitable meshing should have the capability of adapting with main flow parameters. because the number of total nodes that can be used in numerical simulation is limited, making such grid for complex flows is almost difficult, if it...
متن کاملFlow and Turbulence Modeling and Computation of Shock Buffet Onset for Conventional and Supercritical Airfoils
Flow and turbulence models applied to the problem of shock bu et onset are studied. The accuracy of the interactive boundary layer and the thin-layer Navier-Stokes equations solved with recent upwind techniques using similar transport eld equation turbulence models is assessed for standard steady test cases, including conditions having signi cant shock separation. The two methods are found to c...
متن کاملNumerical Simulation of Transonic Buffet on Swept Wing of Supercritical Airfoils
This paper presents transonic buffet simulations over a swept wing of supercritical airfoils with Unsteady Reynolds-Averaged Navier-Stokes (URANS) and Detached-Eddy Simulation (DES) methods. The NASA SC(2)-0714 airfoil is used as wing profile. Computations are conducted at free-stream Mach numbers from 0.72 to 0.84 for Reynolds number 45.0 × 10 based on aerodynamic chord length. Firstly, 2D NAS...
متن کاملCoda: Transonic Airfoils and SLE
We close by describing two rather unusual applications of complex variables. The details are beyond the scope of this book, but the ideas involved definitely deserve mention. The first area of application is fluid dynamics. It was observed already in the nineteenth century that the equations describing the incompressibility and irrotationality of fluids are just the Cauchy-Riemann equations for...
متن کاملMultiple Solutions and Buffet of Transonic Flow over the NACA0012 Airfoil
Multiple solutions of the small-disturbance potential equation and the full potential equation were known for the NACA0012 airfoil in a certain range of transonic Mach numbers and at zero angle of attack. However the multiple solutions for this particular airfoil were not observed using Euler or Navier-Stokes equations under the above flow conditions. In the present work, both the Unsteady Reyn...
