Numerical Verification of Scaling Laws for Shock-Boundary Layer Interactions in Arbitrary Gases
(The American Society of Mechanical Engineers (ASME), 1997)The steady, two-dimensional interaction of an oblique shock with a laminar flat-plate boundary layer has been examined through use of the Beam-Warming implicit scheme. A wide range of fluids ... -
Energy Separation in a Jet Flow
(The American Society of Mechanical Engineers (ASME), 1997)Fluids in motion can separate into regions of higher and lower energy (temperature); this is called “energy separation.” The present study concerns the mechanism of energy separation in a free, ... -
Stokes Flow Through a Transversely Finned Channel
(The American Society of Mechanical Engineers (ASME), 1997)The efficient method of eigenfunction expansion and point match is used to solve the Stokes flow through a channel with transverse fins. Both in-phase and staggered fins are considered. Streamlines ... -
Predictions of Impacting Sonic and Supersonic Jets
(The American Society of Mechanical Engineers (ASME), 1997)A mathematical model of sonic and supersonic jets, validated previously by the present authors for the prediction of moderately and highly underexpanded free jets, is used to simulate the near ... -
Flow Driven by a Torsionally-Oscillating Shrouded Endwall Disk
(The American Society of Mechanical Engineers (ASME), 1997)A study is made of time-dependent flow of a viscous fluid driven by an oscillating shrouded disk in finite geometry. Numerical solutions to the Navier-Stokes equations are obtained for the ... -
On the Slightly Reduced Navier-Stokes Equations
(The American Society of Mechanical Engineers (ASME), 1997)In this paper the so-called slightly reduced Navier-Stokes (SRNS) equations with most streamwise viscous diffusion and heat conduction terms are investigated in detail. It is proved that the ... -
Flow Field Unsteadiness in the Tip Region of a Transonic Compressor Rotor
(The American Society of Mechanical Engineers (ASME), 1997)An experimental investigation concerning tip flow field unsteadiness was performed for a high-performance, state-of-the-art transonic compressor rotor. Casing-mounted high frequency response pressure ... -
Numerical Analysis of Unsteady Flow in the Weis-Fogh Mechanism by the 3D Discrete Vortex Method With GRAPE3A
(The American Society of Mechanical Engineers (ASME), 1997)The three-dimensional flows in the Weis-Fogh mechanism are studied by flow visualization and numerical simulation by a discrete vortex method. In this mechanism, two wings open, touching their ... -
Effects of Bulk Flow Pulsations on Film-Cooled Boundary Layer Structure
(The American Society of Mechanical Engineers (ASME), 1997)Experimental results are presented which describe the effects of bulk flow pulsations on film cooled boundary layer structure. The film is produced by a single row of simple angle film cooling ... -
Turbulent Near Wake Behind a Partially Grooved Circular Cylinder
(The American Society of Mechanical Engineers (ASME), 1997)The near wake of a partially V-grooved circular cylinder is investigated. The flow over the smooth half is within the high subcritical regime, while that over the grooved half is within the ... -
Oscillatory Momentum Transport Mechanisms in Transitional Complex Geometry Flows
(The American Society of Mechanical Engineers (ASME), 1997)This work reports direct numerical simulations of transitional flows in communicating channels. Above a critical Reynolds number, the flow becomes fluctuating and self-sustained with vortical motions ... -
The Effect of Pressure Gradients on Transition Zone Length in Hypersonic Boundary Layers
(The American Society of Mechanical Engineers (ASME), 1997)Boundary layer transition was measured in zero, favorable, and adverse pressure gradients at Mach 8 using heat transfer. Models consisted of 7° half angle forecones 0.4826 m long, followed ... -
Boundary Layer Flow About and Inside a Liquid Sphere
(The American Society of Mechanical Engineers (ASME), 1997)A finite-difference scheme has been developed to solve the boundary-layer equations governing laminar flows around and inside a spherical fluid droplet moving steadily in another immiscible fluid. ... -
Effects of Convection and Decay of Turbulence on the Wall Pressure Wavenumber-Frequency Spectrum
(The American Society of Mechanical Engineers (ASME), 1997)Cross-spectral and cross-correlation data from experiments and numerical simulations have shown the turbulent wall pressure convection velocity to vary with the streamwise sensor spatial separation. ... -
Review: Hot-Wire Anemometry in Transonic and Subsonic Slip Flows
(The American Society of Mechanical Engineers (ASME), 1997)In the past, only a relatively small number of investigations were conducted using hot-wire anemometry in transonic and subsonic slip flows. This was due to the complexity of the applicable ... -
