The transonic safe mode as an enabler of next-generation wind turbines [PDF]
The wind energy industry is moving towards larger and more powerful turbines, with next-generation designs expected to operate at blade tip speeds exceeding 100 m s −1.

Numerical Study of the Lift Enhancement Mechanism of Circulation Control in Transonic Flow
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,

Multidimensional transonic shock waves and free boundary problems
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
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.

Shock Wave Capturing Numerically in Two Dimensional Supersonic Wind Tunnel for Different Configuration [PDF]
Numerical solutions of two dimensional Euler equations are obtained for transonic and supersonic flows. The shock capturing method is employed to solve compressible Euler equations by using MacCormack's time marching method that an explicit finite ...

Transonic magnetohydrodynamic flows [PDF]
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 ...

Transonic Buffet Active Control with Local Smart Skin
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.

Importance of Air Humidity and Contaminations in the Internal and External Transonic Flows
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
