Book On the Instability of Hypersonic Flow Past a Flat Plate

Download or read book On the Instability of Hypersonic Flow Past a Flat Plate written by Institute for Computer Applications in Science and Engineering and published by . This book was released on 1990 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The instability of hypersonic boundary-layer flows over flat plates is considered. The viscosity of the fluid is taken to be governed by Sutherland's law, which gives a much more accurate representation of the temperature dependence of fluid viscosity at hypersonic speeds than Chapmans's approximate linear law; although at lower speeds the temperature variation of the mean state is less pronounced so that the Chapman law can be used with some confidence. Attention is focussed on the so-called vorticity mode of instability of the viscous hypersonic boundary layer. The instability of the hypersonic boundary layer is non-interactive. The vorticity mode of instability of this flow operates on a significantly different lengthscale than that obtained if a Chapman viscosity law is assumed. The growth rate predicted by a linear viscosity law overestimates the size of the growth rate by O (M-sq). Next, the development of the vorticity mode as the wavenumber decreases is described, and it is shown that acoustic modes emerge when the wavenumber has decreased from it's O(1) initial value to O (M to the -3/2 power).

Book A Flat Plate Study of the Binary Scaling of Viscous Hypersonic Flow

Download or read book A Flat Plate Study of the Binary Scaling of Viscous Hypersonic Flow written by D. J. Harney and published by . This book was released on 1971 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between the inviscid field and the large viscous boundary layer characteristic of hypersonic flow is analyzed from the continuum viewpoint. A variety of similarity parameters are derived to represent the viscous flow over slender bodies. The similitude is described by a binary collision scaling parameter, so that it is possible to apply a binary scaling that transforms density and length in inverse proportion at a fixed velocity and temperature. Experiments at a Mach number near 13 on a thermally controlled copper sharp plate were conducted to examine the wall temperature effects. Because of the wide range of test conditions covered in the experiments, the results provide some insight into viscous similarity when molecular effects begin to appear at the leading edge.

Book On Hypersonic Viscous Flow Near a Sharp Leading Edge

Download or read book On Hypersonic Viscous Flow Near a Sharp Leading Edge written by Richard W. Garvine and published by . This book was released on 1966 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical inquiry is made into the high speed viscous flow past a sharp-edged flat plate whose surface is aligned with the oncoming flow. Basic information is sought concerning the fundamental nature of the flow field in regions near the leading edge. The role of upstream conditions is found to be fundamental. Study is made of the viscous layer region on the two-dimensional flat plate ahead of the strong interaction region. The Navier-Stokes equations are applied to the flow up to the point where continum treatments are no longer justifiable. Two initial velocity profiles were assumed in order to examine the details of the theory. Neither form proved to yield realistic flow fields in the light of experimental results. Computations from these two profile forms, however, did serve to bring out the sensitivity of the flow throughout the viscous layer region to initial conditions. It is concluded, in consequence, that the flow cannot be described by similar solutions or other solutions which ignore these initial values. (Author).

Book Investigation of a Hypersonic Flow of Slightly Rarefied Viscous Gas Around a Flat Plate

Download or read book Investigation of a Hypersonic Flow of Slightly Rarefied Viscous Gas Around a Flat Plate written by V. S. Galkin and published by . This book was released on 1963 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculation of drag coefficient of a flat semi-infinite heat-insulated plate in a hypersonic gas flow with slip is described. It is assumed that the region of flow between joined strong jumps of the packing and the plate consists of a non-viscous zone and laminar boundary layer. The strong interaction of the jump with the layer is considered. In calculation of the boundary layer the integral form of equation of pulses with linear profile of speed is used and taking into account the speed of slip. Parameters of flow on the external boundary of the boundary layer are calculated by the method of tangential wedges.

Book Hypersonic Viscous Flow Over Slender Bodies Having Sharp Leading Edges

Download or read book Hypersonic Viscous Flow Over Slender Bodies Having Sharp Leading Edges written by Stanley G. Rubin and published by . This book was released on 1967 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hypersonic viscous pressure interaction is treated by the development of a set of equations valid throughout the boundary layer, shock-wave structure and inviscid core. Primary interest is concerned with the nature of the leading edge continuum merged layer in which the shock wave and boundary layer are indistinguishable. Due to the parabolic nature of the equations, finite-difference solutions are attainable. The flow over a flat plate at zero incidence, as well as angle of attack, was considered. Velocity and state variable distributions across the viscous layer depict the formation of an outer shock wave and inner constant pressure boundary layer. The calculated values of surface pressure, heat transfer and shock jump conditions were at first significantly below the values predicted by strong interaction theory. Agreement was quite good downstream of the merged layer where Rankine-Hugoniot jump conditions were satisfied to within 8%. (Author).

Book Hypersonic Viscous Interaction An Experimental Investigation of the Flow Over Flat Plates at Incidence and Around an Expansion Corner

Download or read book Hypersonic Viscous Interaction An Experimental Investigation of the Flow Over Flat Plates at Incidence and Around an Expansion Corner written by John L. Stollery and published by . This book was released on 1970 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flat plate and expansion corner models were tested over a range of positive and negative incidences in a continuous hypersonic wind tunnel operating at M = 14.8. Surface pressure distributions were obtained for comparison with the viscous interaction theories of Cheng and Sullivan. Since these theories assume 'local flat plate similarity' for the boundary layer flow, pitot pressure profiles were measured at various stations along the plates. It often proved difficult to define the boundary layer edge within the shock layer and total temperature profiles would greatly assist in interpreting the data. Schlieren pictures and oil flow visualization gave good indications of the extent of end effects, the onset of separation caused by the trailing edge shock wave, and tunnel blocking at high model incidence. The tests have provided some new hypersonic experimental data under conditions where both strong viscous interaction and incidence effects are important. (Author).

Book Theoretical and Experimental Studies of Laminar Flow Separation on Flat Plate wedge Compression Surfaces in the Hypersonic Strong Interaction Regime

Download or read book Theoretical and Experimental Studies of Laminar Flow Separation on Flat Plate wedge Compression Surfaces in the Hypersonic Strong Interaction Regime written by Michael S. Holden and published by . This book was released on 1967 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a theoretical and experimental investigation of the properties of attached and separated regions of shock wave-laminar boundary layer interactions in the strong interaction regime. A study was made of the flow over a flat plate-wedge compression surface in the high Mach number, low Reynolds number regime where the interaction between the viscous and inviscid regions over the basic flat plate is 'strong' and of fundamental importance to the problem. The theoretical analysis described in the first part of the paper treats the development of the viscous layer and its interaction with the external inviscid stream, using an integral representation for the boundary layer equations. The analysis describes the strong interaction over the flat plate, the transition from a supercritical to a subcritical boundary layer upstream of the separation point, and the subsequent development of the viscous layer through to the end of the interaction. The theory was compared with experimental measurements in both strong and weak interaction regions of separated flow. The complementary experimental study described in the second part of the paper was designed to investigate the shock wave-boundary layer interaction on flat plate-wedge compression surfaces in the strong interaction regime.
