Turbulence characteristics of an incompressible free jet under the influence of acoustic disturbances
(1988)
An acoustically excited (St = 0.50), Mach 0.15, axisymmetric free jet operating at Reynolds number of 41,000 was studied in order to determine the transition behavior, the overall turbulence characteristics, and to quantify ...
Entrance and exit region friction factor models for annular seal analysis
(1988)
The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal ...
Improved analysis of laminated heterogeneous beams and associated formulation of a new finite element method
(1988)
Kirchhoff's theory for plates and Bernouilli-Euler's theory for beams ignore the effects of transverse shear and normal deformations on stresses and displacements. Various subsequent theories have incorporated these effects ...
Measurements and uses of elastic constants for determining the technical constants and Debye temperature
(1988)
This dissertation deals with the subject of testing the methodology of the PUCOT (Piezoelectric Ultrasonic Composite Oscillator Technique) for measuring the elastic constants, providing an improved method of using sound ...
Determination of the mode I delamination fracture toughness of multidirectional composite laminates
(1988)
The objective of this study is to develop and verify a theoretically-based method for characterizing mode I delamination fracture of composite laminates. Attention focuses on the special problems associated with delamination ...
Analysis of eccentric annular pressure seals : a new solution procedure for determing reactive force and rotordynamic coefficients
(1988)
A new analysis procedure which solves for leakage, reactive force, and rotordynamic coefficients of eccentric annular liquid and gas pressure seals is presented in this dissertation. This analysis procedure is based on a ...
Product design analysis for robotic assembly using extended Group Technology techniques
(1988)
The adaptive ability of robotic assembly systems is often limited by hardware deficiencies. In order to effectively use the available robotic assembly systems, products need to be designed to accommodate current equipment ...
