Smooth Transonic Flows Around Cones

open access: yesNetworks and Heterogeneous Media, 2022
<p style='text-indent:20px;'>We consider a conical body facing a supersonic stream of air at a uniform velocity. When the opening angle of the obstacle cone is small, the conical shock wave is attached to the vertex. Under the assumption of self-similarity for irrotational motions, the Euler system is transformed into the nonlinear ODE system. We

Intermittent Flow Regimes in a Transonic Fan Airfoil Cascade

open access: yesInternational Journal of Rotating Machinery, 2004
A study was conducted in the NASA Glenn Research Center (NASA-GRC) linear cascade on the intermittent flow on the suction surface of an airfoil section from the tip region of a modern low aspect ratio fan blade.

Shear Layer and Wake Characteristics of Square Cylinder in Transonic Flow

open access: yesShanghai Jiaotong Daxue xuebao, 2021
The transonic flow around a square cylinder at Ma= 0.71 and Re= 4×105 has been studied by using the scale-adaptive simulation (SAS) method, and the characteristics of separated shear layer and wake have been analyzed in depth. To validate the SAS

Transonic flow past finite wedges [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 1952
AbstractThe solution for the flow of an incompressible fluid past an infinitely long wedge with a finite sloping edge (a finite wedge) is generalized by the hodograph method. In the flow thus obtained the axis of symmetry and a sloping edge of the wedge are again part of one streamline.

Aerodynamic Parameters Analysis of Transonic Flow Past Unswept and Swept Wings [PDF]

open access: yesEngineering and Technology Journal, 2011
The transonic flow past unswept and swept wings has been studied. For this purpose the transonic potential flow equation is solved for inviscid compressible flow. The shock waves are replaced by discontinuities across which the entropy is conserved.

On transonic flow models for optimized design and experiment

open access: yesEPJ Web of Conferences, 2014
In the paper the near sonic flow theory for flows with small perturbations to sonic parallel flow is developed. This theory stands on the basis of potential flow of a compressible fluid and enables to receive an exact solution of the flow parameters past

Effect of Moist Air on Transonic Internal Flow around a Plate

open access: yesJournal of Fluid Science and Technology, 2009
The unsteady phenomena in the transonic flow around airfoils are observed in the flow field of fan, compressor blades and butterfly valves, and this causes often serious problems such as the aeroacoustic noise and the vibration.
