Analytical and experimental investigation of a dual passage, monogrove heat pipe
(1985)
A parametric study of the forces governing the liquid vapor interface was performed for the purpose of determining the capillary priming characteristics of Grumman's dual passage, monogroove heat pipe when subjected to ...
Development of a 3-D Laser Doppler anemometry system : with measurements in annular and labyrinth seals
(1989)
A 3-D Laser Doppler anemometry system has been developed. This system was specifically developed to make measurements very close to solid surfaces (within .020 mm) in water. This system will allow measurement of mean ...
Finite element analysis of laminar convective heat transfer
(1979)
A finite element method is developed for the analysis of two dimensional, transient laminar convective heat transfer. The method is applied to three classes of problems over a range of flow and thermal conditions. The ...
Analysis and testing for rotordynamic coefficients of grooved turbulent annular seals
(1985)
An analysis for turbulent grooved seals which are the most common design in commercial pumps was developed and tested to predict leakage and dynamic coefficients, as related to rotor- dynamics. The grooved surface roughness ...
Controller synthesis for input-output tracking in Luŕe type uncertain nonlinear systems
(1990)
A very important application of feedback is servo-tracking, or the ability of a closed-loop system to track a given class of reference input signals, while rejecting a given class of external disturbances, in the sense ...
Group combustion of coal particles
(1992)
Most practical combustor systems such as boilers, gas turbines, Diesel engines, rocket engines, etc. use liquid and/or solid fuels as the energy source. Combustion intensity is controlled by the gasification, mixing and ...
Heat transfer in a serpentine channel with a series of right angle turns
(1993)
Heat transfer in a two-dimensional serpentine channel with a series of right angle turns was investigated experimentally and numerically. Similar channel geometry can be found typically in heat exchangers, thermal regenerators, ...
Investigation of heat transfer characteristics and flow reversal phenomena in naturally convecting parallel/converging vertical channel flow
(1993)
The natural convective heat transfer characteristics in parallel/converging vertical channel flows and the flow reversal phenomena in a vertical parallel channel were studied. A sophisticated nonintrusive measurement ...
Thermoelastohydrodynamic tilt pad journal bearing simulation and application to rotor-bearing model
(1993)
A general approach for incorporating heat transfer and elastic deformation effects into a tilt pad journal bearing simulation model is presented. A global analysis method is used, which includes variable viscosity and heat ...
Echelon control for automatic control systems
(1967)
Echelon control has as its goal the control of a single variable through the interaction of a collection of controllers. The objective is that the controllers will work together in a manner such that each has a designated ...
