Hanging an Elastic Ring
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1980), CS80007-R
A thin flexible elastic circular ring is hung at one point. The ring deforms due to its own weight. The problem depends on a non-dimensional parameter B representing the relative importance of density and length to rigidity. ...
A Simple Model for the Average Local Entrainment Rate
(AIP Publishing, 1986-07-01)
A new expression for the mean local entrainment rate in a turbulent intermittent flow is obtained. This expression is used to obtain a simple model for the entrainment rate assuming that an indicator function can be defined ...
Flow Over Bodies with Suction Through Porous Strips
(AIP Publishing, 1986-07-01)
This article addresses the steady, incompressible flow past a two‐dimensional or an axisymmetric body with suction through porous strips. Closed‐form solutions for each flow quantity are developed in the context of linearized ...
Second-order asymptotic solution for laminar separation
(AIP Publishing, 1980)
The method of matched asymptotic expansions is used to obtain a second-order triple-deck solution for the case of constant wall temperature. It includes the problem of an adiabatic wall as a special case. The theory is ...
Exact Numerical Results for Poiseuille And Thermal Creep Flow in a Cylindrical Tube
(AIP Publishing, 1986-02-01)
The F N method is used, in the field of rarefied gas dynamics, to develop a complete solution for the cylindrical Poiseuille flow and thermal creep problems. The linearized Bhatnagar–Gross–Krook (BGK) model and purely ...
Grain-boundary ordering, segregation, and melting transitions in a two-dimensional lattice-gas model
(American Physical Society, 1989-06-01)
A two-dimensional lattice-gas model of a binary-ordering-alloy system was used to study the phase transitions and the atomic configuration near a Σ=5 grain boundary. The cluster variation method was used to study order-disorder ...
Dynamic response of cross-ply laminated shallow shells according to a refined shear deformation theory
(Acoustical Society of America, 1989-06-01)
The dynamic response of cross-ply laminated shallow shells is investigated using the third-order shear deformation shell theory of Reddy [J. Appl. Mech. 4 1, 47 (1984)]. The theory accounts for cubic variation of the ...
Intensity-Induced Quenching of Absorption of Diatomic Molecules in Two Near-Resonance Laser Fields
(American Physical Society, 1982-10-01)
The interaction of a diatomic molecule with two near-resonance laser fields is investigated with the use of a one-dimensional anharmonic oscillator model. Our study shows that, over a certain range of intensity of one of ...
Hyperbolic heat conduction with temperature-dependent thermal conductivity
(American Institute of Physics, 1986-03-15)
Hyperbolic heat conduction in a semi-infinite slab with temperature-dependent thermal conductivity is studied numerically, and the results are compared with those obtained from the classical parabolic equation for the ...
Noncontacting Detection in Ultrasonic Nondestructive Evaluation Of Materials: Simple Optical Sensor And Fiberoptic Interferometric Application
(AIP Publishing, 1986-09-01)
An optical displacement sensor based on the two_beam interferometry of coherent light using two principal diffracted orders of a fine reflection blazed grating is constructed. The inherent capability of the interferometer ...
