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.

On transonic viscous–inviscid interaction [PDF]
Journal of Fluid Mechanics, 2002 The paper is concerned with the interaction between the boundary layer on a smooth body surface and the outer inviscid compressible flow in the vicinity of a sonic point. First, a family of local self-similar solutions of the Kármán–Guderley equation describing the inviscid flow behaviour immediately outside the interaction region is analysed; one ...

Structural Stability of the Transonic Shock Problem in a Divergent Three-Dimensional Axisymmetric Perturbed Nozzle [PDF]
SIAM Journal on Mathematical Analysis, 2019 In this paper, we prove the structural stability of the transonic shocks for three dimensional axisymmetric Euler system with swirl velocity under the perturbations for the incoming supersonic flow, the nozzle boundary, and the exit pressure.

Sound radiation and transonic boundaries of a plate with an acoustic black hole.
Journal of the Acoustical Society of America, 2019 The acoustic black hole (ABH) phenomenon has shown promise for noise and vibration control applications. In this paper, a two-dimensional (2-D) Daubechies wavelet (DW) model is established for the sound radiation prediction of plates embedded with a ...

Multidimensional transonic shock waves and free boundary problems
Bulletin of Mathematical Sciences, 2022 We are concerned with free boundary problems arising from the analysis of multidimensional transonic shock waves for the Euler equations in compressible fluid dynamics.

A Unified Asymptotic Theory of Supersonic, Transonic, and Hypersonic Far Fields
Axioms, 2022 The problems of steady, inviscid, isentropic, irrotational supersonic plane flow passing a body with a small thickness ratio was solved by the linearized theory, which is a first approximation at and near the surface but fails at far fields from the body.
