Damping degradation in incramute and sonoston due to low temperature storage.
Two commercial manganese-copper based alloys, SONOSTON and INCRAMUTE, were evaluated for their ability to maintain optimum damping capacity with time when stored at room temperature and 100°C, which represents a temperature ...
Film condensation of steam on low-integral finned tubes with drainage strips
Heat-transfer measurements were made for filmwise condensation of steam under low pressure and at near-atmosphere pressure on horizontal finned tubes attached with bronze porous and solid drainage strips. The effect of ...
The effects of an embedded vortex on a film cooled turbulent boundary layer.
This study was designed to model some of the secondary flow effects on endwalls, blades, and combustion chambers of gas turbine engines. Measurements were made in a turbulent boundary layer developing over a flat plate, ...
Stability of the vortex motion in oscillating flow.
Previous experimental investigations have shown that the characteristics of flow about a circular cylinder immersed in a time-dependent flow exhibit cycle-to-cycle variations. These variations have been attributed to the ...
Modeling and experimental validation of a single-link flexible manipulator.
Structural flexibility effects on robot mechanisms is a very important consideration in the move toward lighter, faster, and more accurate robot systems. This thesis presents the computer simulation and experimental ...
Microcomputer control of a hydraulic power element
The Navy uses electrohydraulic servomechanisms throughout the fleet in the control of vehicles, weapons, and platforms. Better understanding of how these systems work will lead to ways of improving their performance, ...
A calorimetric study of the microstructures of a thermomechanically processed Al-10.0% Mg-0.1% Zr alloy.
DifTerential scanning calorimetry (DSC) was used to investigate microstructure evolution in a high-magnesium aluminum-magnesium alloy, Al-10.0% Mg-0.1% Zr, which had been thermomechanically processed. The two variations ...
A correlation for the heat transfer coefficent in a rectangular passage containing protuberance
An experimental investigation was carried out to determine the effect on the convective heat transfer coefficient of protuberances in a rectangular passage. A cross-flow compact type heat exchanger formed by several ...
Marine gas turbine modeling for modern control design
The search for improved performance of U.S. Navy ships has led to more complex propulsion systems consisting of multiple, interacting inputs. Classical control theory does not effectively exploit these interactions. Modern ...
Computer simulation and experimental validation of a dynamic model (equivalent rigid link system)--on a single-link flexible manipulator.
Flexibility effects on robot manipulator design and control are typically ignored which is justified when large, bulky robotic mechanisms are moved at slow speeds However, when increased speed and improved accuracy ...
