Numerical analysis of the flow pattern and vortex breakdown over a pitching delta wing at supersonic speeds
M. Hadidoolabi, H. Ansarian Malek Ashtar University of Technology, Tehran, Iran
Abstract:
A supersonic compressible flow over a 60$^\circ$ swept delta wing with a sharp leading edge undergoing pitching oscillations is computationally studied. Numerical simulations are performed by the finite volume method with the use of the $(k{-}\omega)$ turbulence model for various Mach numbers and angles of attack. Variations of flow patterns in a crossflow plane, hysteresis loops associated with the vortex core location, and vortex breakdown positions during a pitching cycle are investigated. Trends for various Mach numbers, mean angles of attack, pitching amplitudes, and pitching frequencies are illustrated.
Keywords:
