Derivation, testing and application of a new multi-scale k-e̳ turbulence model
(1991)
This study discusses the derivation and assessment of a new two-scale dissipation equation, the genesis of which begins with a different fundamental equation than previous multi-scale or single-scale models. The new approach ...
A study of combined heat and mass transfer by free convection from a controlled environment to a plate at -310°F
(1967)
An experimental study of heat and mass transfer in free convection from a controlled environment to a plate at liquid nitrogen temperature (-310°F) has been made. The temperature of the environment was varied from 36°F to ...
Transverse shear and normal stresses in laminated beams
(1980)
It is known that the Kirchhoff Theory neglects the effects of transverse stresses on the displacement functions. Thus the validity of Kirchhoff Theory is suspect for laminated beams if the material properties vary significantly ...
Birefringent coating analysis of a particulate composite
(1971)
This study, using the method described by Hartley and Rao [10], derives confidence regions for the ratios of variances in random model. Each region is compared with a confidence region derived by Wald [22]. We derived ...
The evaporation of a thin liquid film from a solid surface
(1971)
Essentially two basic theories attempt to account for the heat flux in nucleate pool boiling. The first theory assumes that the larger fraction of thermal energy transfer results from the disturbance by bubble action of ...
Radiant heat transfer between gray surfaces forming an enclosure
(1965)
An analytical investigation was made of the radiant heat transfer between the surfaces of a gray enclosure filled with a non-reacting gas considering all multiple reflections between the surfaces. The problem was developed ...
Load-induced rotordynamic instabilities in turbomachinery
(1984)
By employing the extended Hamilton principle, both equations of motion and associated boundary conditions are derived for three different models subjected to non-conservative torques: the cantilevered rotor, the uniform ...
Effect of fluid inertia on squeeze film damper force response
(1985)
The effect of fluid inertia on the force response of Squeeze Film Dampers (SFD) is a subject of great importance since most existent damper applications operate with Reynolds numbers in the range of one to ten. For small ...
Structural optimization utilizing approximated structural behavior
(1973)
This dissertation presents an investigation of the feasibility of using approximated structural behavior in the optimization of plane truss and plane frame structures. Design variables are limited to the cross-sectional ...
