Numerical Comparison between Physics of Transitional Flow and Full Turbulent Flow around Classical Airfoil of NACA0012 at Subsonic and Transonic Regimes

In the following paper, the accuracy of full turbulent K-e and transitional K-w models in external aerodynamic capturing of NACA0012 and sensitivity analysis have been comprehensively investigated. Among these investigations, some sorts of sensitivity analysis, including changes in free-stream Mach number, free-stream Reynolds number, free-stream angle of attack and generated-grid density have been done. Also the effects of transition inception point and the magnitude of the conformity between numerical results and theoretical concepts about transition and related effective parameters on the magnitude of lift, drag, lift-slope, pressure distribution, and pressure/friction lift-and-drag coefficients have been investigated in detail. To confirm the validity and the accuracy of the results, the numerical results have been compared with some published references.
