Transonic Buffet Active Control with Local Smart Skin
Actuators, 2022 Transonic flight has high economic benefits, but the appearance of transonic buffet limits the flight envelope. The shock control bump currently used for transonic buffet suppression tends to degrade the aerodynamic performance of the non-buffeting state.

Double phase transonic flow problems with variable growth: nonlinear patterns and stationary waves [PDF]
Nonlinearity, 2019 In this paper we are concerned with a class of double phase energy functionals arising in the theory of transonic flows. Their main feature is that the associated Euler equation is driven by the Baouendi–Grushin operator with variable coefficient.

Importance of Air Humidity and Contaminations in the Internal and External Transonic Flows
Energies, 2020 The paper presents mathematical modelling of steam condensation in the atmospheric air transonic flows. A single-fluid model was employed. The model was validated against the in-house experimental studies of internal flow in nozzles and against benchmark

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

Transonic magnetohydrodynamic flows [PDF]
Journal of Plasma Physics, 1997 Stationary flows of an ideal plasma with translational symmetry along the (vertical) z axis are considered, and it is demonstrated how they can be described in the intrinsic (natural) coordinates (ξ, η, &), where ξ is a label of flux and stream surfaces, η is the total pressure and ϑ is the angle between the horizontal magnetic (and ...

Effect of Humidity on Transonic Flow [PDF]
Journal of Aircraft, 2008 An experimental investigation of the effects of humidity-induced condensation on shock/boundary-layer\ud interaction has been conducted in a transonic wind-tunnel test. The test geometry considered was a wall-mounted\ud bump model inserted in the test section of the wind tunnel.

Periodic transonic flow and control [PDF]
The Aeronautical Journal, 2008 AbstractThe current understanding of periodic transonic flow is reviewed briefly. The effects of boundary-layer transition, non-adiabatic wall conditions and modifications to the aerofoil surface geometry at the shock interactions on periodic transonic flow are discussed.

Numerical Study of the Lift Enhancement Mechanism of Circulation Control in Transonic Flow
Aerospace, 2021 The lift of an aircraft can be effectively enhanced by circulation control (CC) technology at subsonic speeds, but the efficiency at transonic speeds is greatly decreased. The underlying mechanism of this phenomenon is not fully understood. In this study,
