DOI: 10.1016/j.ast.2018.03.045
Abstract: Abstract Within a narrow band of flight conditions in the transonic regime, self-sustained shock oscillations that involve the interaction between shock-waves and intermittently separated shear layers may develop. This phenomenon, known as transonic shock buffet,… read more here.

DOI: 10.1016/j.cja.2019.12.022
Abstract: Abstract In transonic flow, buffet is a phenomenon of flow instability caused by shock wave/boundary layer interaction and flow separation. The phenomenon is common in transonic flow, and it has serious impact on the structural… read more here.

DOI: 10.1017/jfm.2020.848
Abstract: Abstract This paper examines the three-dimensional cellular patterns appearing on wings in subsonic stall and transonic buffet conditions. Unsteady Reynolds-averaged Navier–Stokes simulations are carried out for three-dimensional infinite swept configurations closed by periodic boundary conditions… read more here.

DOI: 10.2514/1.j056855
Abstract: The dominant fluid structures and unsteady behavior of the three-dimensional transonic buffet phenomenon on a swept wing are clarified. This paper focuses on a well-established buffet phenomenon rather than an incipient shock buffet (buffet onset).… read more here.

DOI: 10.3390/app9194132
Abstract: Transonic buffet not only influences the structural integrity, handling quality and ride comfort, but also limits the flight envelope of transporters and airliners. To delay buffet onset and alleviate the buffet load, the effects of… read more here.
