A Reliable Algorithm for a Local Fractional Tricomi Equation Arising in Fractal Transonic Flow

open access: yesEntropy, 2016
The pivotal proposal of this work is to present a reliable algorithm based on the local fractional homotopy perturbation Sumudu transform technique for solving a local fractional Tricomi equation occurring in fractal transonic flow.

Viscosity Influence on Flutter Boundary and Limit Cycle Oscillation in Transonic Regime

open access: yesJournal of Fluid Science and Technology, 2008
Viscosity has a great influence on nonlinearity especially in the transonic regime: however only preliminary research into the viscous effect on the aeroelstic response was conducted. Nonlinearity of the flowfield assumed to be the main source of flutter

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.

Study of transonic effect of flows around slender bodies of revolution and plane profiles

open access: yesVietnam Journal of Mechanics, 2010
Transonic effect with presence of local supersonic terminated by shock wave is not wished. In spite of wishes or not, the appearance of shock waves is not avoided.

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

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.

Vane-Probe Interactions in Transonic Flows

open access: yesVolume 2: Coal, Biomass, Hydrogen, and Alternative Fuels; Controls, Diagnostics, and Instrumentation; Steam Turbine, 2022
Abstract In this paper, a numerical investigation of the effect of a miniaturized five-hole probe downstream of a transonic low-pressure turbine vane row is presented. Firstly, a numerical calibration of the probe was performed in uniform flow conditions, as is the case for any traditional calibration, for a wide range of ...

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
