On an Exact Step Length in Gradient-Based Aerodynamic Shape Optimization—Part II: Viscous Flows
Fluids, 2021 This study presents an extension of a previous study (On an Exact Step Length in Gradient-Based Aerodynamic Shape Optimization) to viscous transonic flows. In this work, we showed that the same procedure to derive an explicit expression for an exact step

Computational transonics [PDF]
Communications on Pure and Applied Mathematics, 1988 This paper is written to commemorate the sixitieth birthday of Paul Garabedian. As flight speed increased to the point that the flow was dominated by compressibility effects, the focus moved to transonic flow, and it was in this field that Paul Garabedian's contributions were particularly significant.

Spectral Energy of High-Speed Over-Expanded Nozzle Flows at Different Pressure Ratios
EnergiesThis paper addresses the long-standing question of understanding the origin and evolution of low-frequency unsteadiness interactions associated with shock waves impinging on a turbulent boundary layer in transonic flow (Mach: 1.1 to 1.3).
