Bifurcations in the transonic flow past a symmetric airfoil. (English. Russian original) Zbl 1200.76074

Fluid Dyn. 41, No. 4, 629-632 (2006); translation from Izv. Ross. Akad. Nauk, Mekh. Zhidk. Gaza 2006, No. 4, 160-163 (2006).
Summary: Transonic flow past an airfoil with a small curvature in its midchord region is numerically investigated. The branching of the stationary solutions of the Euler equations is established and attributed to flow instability at certain angles of attack and freestream Mach numbers. The dependence of the lift coefficient on these parameters is studied.
