Comparative Study of Turbulence Models for the Simulation of Three-Dimensional Transonic Flow around Airfoils
Abstract: The analysis of three dimensional transonic flows was carried out on the well-known ONERA M6 airfoil. In this paper three turbulence models i.e. Spalart-Allmaras, k-ω shear stress transport (SST) and k-ε Realizable were compared for transonic flows and validated through comparison with the experimental measurements and CFD results obtained from NASA ONERA M6 study for the selected wing. The discretization of the computational domain was done using an unstructured mesh, …

Transonic Flow Past Conically Cambered Wings
Abstract: The flow is analysed over conically cambered wings for transonic flow conditions. Wing Planform is conically cambered for supersonic flow for minimum induced drag. The circulation to determine the forces is developed using panel methods. Objective function for drag minima is formed using Lagrange multipliers. The transonic flow computations are progressed through computational fluid dynamics. In case of a subsonic leading edge in supersonic flow there is no shock wave …

Study on a Supercritical Airfoil with Variation in Thickness for Improved Aerodynamic Characteristics in Transonic Regime
Abstract: In this research the steady state analysis of a supercritical airfoil is done to understand the flow physics at transonic Mach number regime for various thickness. The modeling of NASA SC (2) 0714 supercritical airfoil with various thickness values is done. The steady state analysis is carried out for different test cases in combination with different thickness, angle of attack and Mach number at 10 km altitude using density-based Reynolds …

Study on the Method of Constructing a System of Linear Equations for Calculating Aerodynamic Derivatives
Abstract: The aerodynamic derivatives can be calculated from the unsteady hydrodynamic forces experienced by the harmonic-oscillating vehicle. Until now, unsteady flow field analysis in aerodynamic derivative calculations has been applied mainly to thin bodies based on potential theory MSC. Nastran is a typical application based on potential theory MSC. Natran can calculate the aerodynamic derivatives of the vehicle relatively well in the subsonic region, but in the supersonic region, the fuselage …
