This article reviews stability and laminar-turbulent transition in high-speed boundary-layer
flows, emphasizing qualitative features of the disturbance spectrum leading to new …

▪ Abstract Parabolized stability equations (PSE) have opened new avenues to the analysis
of the streamwise growth of linear and nonlinear disturbances in slowly varying shear flows …

A modern treatment of hypersonic aerothermodynamics for students, engineers, scientists,
and program managers involved in the study and application of hypersonic flight. It assumes …

Two decades ago when we wrote Spectral Methods in Fluid Dynamics (1988), the subject
was still fairly novel. Motivated by the many favorable comments we have received and the …

The term dynamic stall refers to unsteady flow separation occurring on aerodynamic bodies,
such as airfoils and wings, which execute an unsteady motion. The prediction of dynamic …

Experimental and theoretical studies of the effect of an ultrasonically absorptive coating
(UAC) on hypersonic boundary-layer stability are described. A thin coating of fibrous …

Crossflow instability of a three-dimensional boundary layer is a common cause of transition
in swept-wing flows. The boundary-layer flow modified by the presence of finite-amplitude …

Laminar–turbulent transition mechanisms for a supersonic boundary layer are examined by
numerically solving the governing partial differential equations. It is shown that the dominant …

The existing database of transition measurements in hypersonic ground facilities has
established that as the nose-tip bluntness is increased the onset of boundary-layer transition …

The initial phase of hypersonic boundary-layer transition comprising excitation of boundary-
layer modes and their downstream evolution from receptivity regions to the unstable region …
