Partial Acoustic Filtering Applied to the Equations of Compressible Flow
(The American Society of Mechanical Engineers (ASME), 1991)Gas contained in a rectangular laser cell of large length and small width is subjected to large, transient, spatially nonuniform, volumetric heating when pumped. The heating time scale is much ... -
Aerodynamic Sensitivity Analysis Methods for the Compressible Euler Equations
(The American Society of Mechanical Engineers (ASME), 1991)A mathematical formulation is developed for aerodynamic sensitivity coefficients based on a discretized form of the compressible, two-dimensional Euler equations. A brief motivating introduction to ... -
Gravity-Driven Motion of a Layer of Viscoelastic Fluid Around a Horizontal Wire
(The American Society of Mechanical Engineers (ASME), 1991)A theoretical study of the free-surface flow of a viscoelastic fluid around a horizontal cylinder is reported in this paper. The fluid layer has initially a uniform thickness, and, at some ... -

Local Anisotropy in Strained Turbulence at High Reynolds Numbers
(The American Society of Mechanical Engineers (ASME), 1991)It is shown that the hypothesis of local isotropy is implausible in the presence of significant mean rates of strain. In fact, it appears that in uniform shear flow near equilibrium, local ... -
Effect of Suction on the Stability of Supersonic Boundary Layers. Part II—First-Mode Waves
