Experimental Investigation on the Control of Hypersonic Shock Wave/Boundary Layer Interaction Using Surface Arc Plasma Actuators at Double Compression Corner

open access: yesAerospace, 2023
Compression corner shock wave/boundary layer interaction (SWBLI) is a typical shock wave/boundary layer interaction (SWBLI) problem in supersonic/hypersonic flows. In previous studies, the separation flow is usually caused by a single shock wave. However,

Existence of MHD boundary layer hybrid nanofluid flow through a divergent channel with mass suction and injection

open access: yesChemical Engineering Journal Advances, 2023
The aim of this study is to present the existence of two-dimensional steady boundary layer flow of hybrid nanofluid over a diverging channel in the occurrence of an externally applied magnetic field.

Three dimensional laminar boundary layer with small cross-flow [PDF]

open access: yes, 1954
Important problems involving three-dimensional boundary layer occur in almost all internal and external aerodynamic configurations. For many of these, the flow outside the boundary layer may be resolved into a large principal component and a small ...

Effect of a Roughness Element on the Hypersonic Boundary Layer Receptivity Due to Different Types of Free-Stream Disturbance with a Single Frequency

open access: yesEntropy, 2019
The hypersonic flow field around a blunt cone was simulated using a high-order finite difference method. Fast acoustic waves, slow acoustic waves, entropy waves, and vortical waves were introduced into the free-stream to determine the influence of a free-

Research Progress of Microjet Control of Shock Wave/Boundary Layer Interactions in Supersonic Flow Field [PDF]

open access: yesHangkong bingqi, 2022
The phenomenon of shock wave/boundary layer interaction is inevitable in the supersonic flow field. The existence of this phenomenon will have a series of adverse effects on the inner and outer flow fields of the supersonic vehicle.

Some hypersonic intake studies [PDF]

open access: yes, 2006
A 'two dimensional' air intake comprisipg a wedge followed by an isentropic compression has been tested in the Cranfield Gun Tunnel at Mach 8,2. These tests were performed to investigate qualitatively the intake flow starting process. The effects of cowl

On injection-ejection fluid influence through different accelerating porous surfaces on unsteady 2d incompressible boundary layer characteristics [PDF]

open access: yesTheoretical and Applied Mechanics, 2005
Through the porous contour in perpendicular direction, the fluid of the same properties as incompressible fluid in basic flow, has been injected or ejected with velocity who is a function of the contour longitudinal coordinate and time. The corresponding

Secondary instability in boundary-layer flows [PDF]

open access: yesThe Physics of Fluids, 1979
The stability of a secondary Tollmien–Schlichting wave, whose wavenumber and frequency are nearly one half those of a fundamental Tollmien–Schlichting instability wave, is analyzed using the method of multiple scales. Under these conditions, the fundamental wave acts as a parametric exciter for the secondary wave. The results show that the amplitude of

Heat transfer analysis of boundary layer flow

open access: yesAlexandria Engineering Journal, 2016
In the present study heat transfer and entropy generation analysis of boundary layer flow of an incompressible viscous fluid over hyperbolic stretching cylinder are taken into account. The governing nonlinear partial differential equations are normalized
