Natural convection liquid immersion cooling of high density columns of discrete heat sources in a vertical channel.
(Monterey, California. Naval Postgraduate School, 1989-06)
Natural convection liquid cooling of simulated electronic components in a vertical channel was investigated. The test surface consisted of three columns of fifteen flush mounted foil heaters. The channel was formed by ...
The development and structural characteristics of Dean vortices in a curved rectangular channel
(1988-09)
The development and structure of Dean vortices in a
curved channel were measured and studied. A 40:1 aspect
ratio channel with mild curvature was employed. Circulation
of mean streamwise vorticity, and maxima of ...
Separation in time-dependent flow
(1988-09)
The angular motion of separation points on a smooth cylinder
immersed in a sinusoidally oscillating flow has been determined
experimentally through the use of a U-shaped water tunnel, a special
differential pressure ...
Unsteady flow about porous cambered plates
(1988-06)
The investigation dealt with the numerical and experimental investigation of the effect of porosity on the vortex shedding from a cambered plate.The effect of Dorosity was incorporated into the analysis through the use of ...
Feasibility study of a microprocessor controlled actuator test mechanism
(Monterey, California. Naval Postgraduate School, 1988-03)
This thesis describes the investigation of the feasibility of using a commercially available microcomputer to control and test a missile fin actuator. Topics discussed include system modelling, automated data acquisition, ...
A study of model based maneuvering controls for autonomous underwater vehicles
(1987-12)
Autonomous Underwater Vehicles (AUV) are being considered by the U.S. Navy for a variety of missions. Requirements for autonomy reinforce the need for a robust maneuvering controller that can ensure accurate tracking of a ...
Interaction of a vortex pair with a free surface.
(1987-09)
The trailing vortices generated by the control planes of submarines give rise to surface signatures in the form of scars and striations.
Two counter-rotating vortices were generated in a novel experimental system and their ...
An investigation of the hot corrosion protectivity behavior of platinum modified aluminide coatings on nickel-based superalloys.
(Monterey, California: U.S. Naval Postgraduate School, 1987-03)
The adverse operating environments encountered by
marine gas turbine components has necessitated the
development of various protective coating systems.
Diffusion aluminide coatings have been used successfully for
many ...
Experimental investigation of the effect of curature on heat transfer in a curved rectangular channel of high aspect ratio.
(1987)
An experimental investigation was conducted to study convective heat transfer in
straight and curved rectangular channels of high aspect ratio that approximate plates
of infinite extent. Experiments were performed at steady ...
A multibody dynamic analysis of the N-ROSS satellite rotating flexible reflector using Kane's method.
(1987)
The Navy Remote Ocean Sensing System ( N-ROSS ) satellite is being developed
to supply accurate data on ocean parameters for fleet operations. A Low Frequency
Microwave Radiometer ( LFMR ), a large flexible reflector ...
