Influence of curvature upon the heat transfer from cylinders to gas streams parallel to the axis
(Chicago, Illinois: Illinois Institute of Technology, 1951-06)
It is the purpose of the work to determine the effect of curvature of a round cylindrical surface not surrounded by an enclosure, with the fluid flowing parallel to the surface generators, on the heat transfer by forced ...
An experimental evaluation of the thermal performance of a rotating heat pipe with internal axial fins
(1983-06)
A rotating heat pipe was tested using two different copper condensers (a smooth cylinder and a cylinder with 22 straight axial fins) and water as the working fluid. The smooth condenser was tested at rotational speed of ...
The heat transfer coefficient of a magnetic fluid
(Annapolis, Maryland: Naval Postgraduate School, 1949)
Lattice Boltzmann Methods for Fluid Structure Interaction
(Monterey, California. Naval Postgraduate School, 2012-09)
The use of lattice Boltzmann methods (LBM) for fluid flow and its coupling with finite element method (FEM) structural models for fluid-structure interaction (FSI) is investigated. A body of high performance LBM software ...
Coupled Finite Element and Cellular Automata Methods for Analysis of Composite Structures in an Acoustic Domain
(Monterey, California. Naval Postgraduate School, 2012-09)
This study examines various computational techniques to analyze dynamic response and failure of sandwich composite materials subject to fluid-structure interaction characterized by an acoustic field or the propagation of ...
Effect of two stress raisers acting together at a point
(Monterey, California: U.S. Naval Postgraduate School, 1960)
Stress concentration factors are valuable tools for the machine designer when they can be accepted as reliable. When one stress concentration configuration, such as a hole, fillet, notch, machine finish, etc. exists there ...
Model based design and verification of a rapid dive controller for an Autonomous Underwater Vehicle
(Monterey, California. Naval Postgraduate School, 1989-03); NPS 69-89-04
Autonomous Undervvater Vehicles are being considered
today by many organizations as a lovv cost substitute for
manned vehicles. Requirements forautonomy emphasize
the need for a robust system controller that can ...
FAILURE MODEL FOR FIBROUS COMPOSITES USING MULTISCALE MODELING
(Monterey, CA; Naval Postgraduate School, 2018-06)
An established multiscale model for materials is used as the basis for a failure model for fiber composites. The model’s computation is explained so that its results can be used to formulate the inputs to the failure model. ...
Nonlinear estimation with sparse temporal measurements
(Monterey, California: Naval Postgraduate School, 2016-09)
Nonlinear estimators based on the Kalman filter, the extended Kalman filter (EKF) and unscented Kalman filter (UKF) are commonly used in practical application. The Kalman filter is an optimal estimator for linear systems; ...
Control strategy: wind energy powered variable chiller with thermal ice storage
(Monterey, California: Naval Postgraduate School, 2014-12)
This study commissioned a variable speed chiller system powered by renewable energy with ice thermal storage. A control strategy was also developed that matched the chiller load to any available renewable power. These ...
