Performance of small thrusters and propulsion systems
(Monterey, California: Naval Postgraduate School, 1990-03)
Performance tests of the longitudinal and lateral propulsion devices for use on the Naval Postgraduate School (NPS) Autonomous Underwater Vehicle (AUV) II are presented. The propulsion requirements for the AUV are discussed ...
Effect of surface coating on cylinders subjected to underwater shock
(Monterey, California. Naval Postgraduate School, 1992-09)
The response of a composite cylinder (metallic cylinder coated with a rubber material) subjected to an underwater explosion was analyzed numerically. Qualitative differences between coated and uncoated cylinders were ...
Void fraction in parallel channel boiling water reactors with application to two-phase turbulent mixing
(Cambridge, Massachusetts; Massachusetts Institute of Technology, 1970-06)
An experiment using air-water mixtures to model steam-water flow in a reactor was devised to determine the turbulent mixing mass flow rates between two multichannels over a wide range of flow conditions and therefrom predict ...
Stress distribution in pipe ells with straight end extensions under internal pressure
(Monterey, California: U.S. Naval Postgraduate School, 1954)
The experimental investigation of stresses in steel pipe ells under internal static pressure, herein reported, was conducted at the U. S. Naval Postgraduate School from January to April 1954.
Stress analysis of ceramic gas turbine blades by the finite element method. Part I.
(1978)
The search for more efficient gas turbine engines
has led to the proposal for the replacement of metal
high temperature components with ceramic components
.
Essential to this effort is the numerical analysis of
proposed ...
Numerical prediction of the impact of non-uniform leading edge coatings on the aerodynamic performance of compressor airfoils
(Monterey, California. Naval Postgraduate School, 2004-06)
A computational fluid dynamic (CFD) investigation is presented that provides predictions of the aerodynamic impact of uniform and non-uniform coatings applied to the leading edge of a compressor airfoil in a cascade. Using ...
An analytical and experimental analysis of a linear damping dynamic vibration absorber
(Annapolis, Maryland. U.S. Naval Postgraduate School, 1949)
The theory of the damped dynamic vibration absorber, neglecting the effect of damping in the main mass system, has been worked out and is available in the literature. However, a search of the literature reveals a lack of ...
Added mass of submerged objects of arbitrary shapes
(Monterey, California. Naval Postgraduate School, 1972-09)
Hydrodynamic loads induced on large underwater structures
by Impulsive motion may be significant design factors. Such
loads may be induced by earthquake excitation or may result
from acceleration produced while lifting ...
Optimization of beams for lateral buckling
(Monterey, California ; Naval Postgraduate School, 1971-12)
The treatise seeks to find the optimum shape of a thin
beam under the influence of lateral buckling. The specific
formulation is by means of the isoperimetric problem of the
calculus of variations. An energy method ...
The influence of temperature and composition on the activation energy for creep in binary aluminum lithium alloys
(Monterey, California: Naval Postgraduate School, 1990-12)
With the fast pace of technology in the aerospace industry, there are increasing demands for higher strength and stiffness in structural materials but with reduced weight and improved formability. Aluminum alloys have been ...
