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.

Experimental and Computational Investigation of an “Open” Transonic Cavity Flow [PDF]
, 2009 This paper presents an investigation of a transonic flow (M∞ = 0.85) over a rectangular cavity having a length-to-depth ratio of 5. Velocities were measured inside the cavity on the central plane and two off-centre planes using a two-component particle ...

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

Characteristic prediction method of transonic axial flow turbine
Zhongguo Jianchuan Yanjiu, 2021 ObjectivesRegarding transonic flow occurring at the throat of the stator blades of axial flow turbines at high subsonic and transonic speeds, it is will need a long period of time to have 3D reseach and to obtain the characteristic parameters. Therefore,

Periodic transonic flow and control [PDF]
, 2008 The 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 ...

Calculation of transonic flows around profiles with blunt and angled leading edges
Vietnam Journal of Mechanics, 2016 Transonic flow is a mixed flow of subsonic and supersonic regions. Because of this mixture, the solution of transonic flow problems is obtained only when solving the differential equations of motion with special treatments for the transition from ...

Airfoil seсtion in the near-sonic flow of gas
Авіаційно-космічна техніка та технологія, 2021 The subject of investigation in this article is transonic flow. This is a condition in which local speeds of sound are appears on the wing surface, even at the subsonic speed of the nonturbulent flow. As a result, at a certain speed of the incoming flow,
