A mathematical model is derived to provide quasi-steady state predictions of the performance of a high pressure hydraulic supply system, using equations which govern the physical processes as opposed to equations which match input-output...
A computer model has been developed to analyze the flow of a dissociating gas through a porous metal matrix. The program predicts the transient temperature distributions through the coolant gas and matrix along with the pressure distribution and...
Based on a two-phase boundary layer approach, a computational model is proposed to estimate the thickness of the waterfilm due to rain on the upper surface of an airfoil. The coupling between the air boundary layer and the water film is established...
The equations of underwater acoustics that relate to the signal excess noise received by a transducer are rigorously described in the acoustical literature. The objective of this paper is to examine some underwater acoustic equations and ascertain...
This research evaluates the applicability to microcomputers of various methods for determining the solution of large systems of simultaneous linear algebraic equations. Such systems of equations characterize physical systems often encountered in...
Solar cells have traditionally been used for a direct sunlight to energy conversion, and there has been relatively little investigation into their use as a low data rate optical detector. This report summarizes the results of experimental work to...
While some of think of our cars as simply "buckets of bolts", the proper design choices, applications, and assemblies of threaded fasteners/bolted joints play critical roles in automobile safety. Supplemental Restraint Systems (SRS), more commonly...
A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model ofr the problem is the...
The purpose of this paper was to design a simplified wind tunnel force balance for use in elementary aerodynamics/wind tunnel laboratory courses. The applied loads and moments were determined to be as follows: The design lift force is ± 20 lbs,...
A computer model of a flat plate solar collector has been devised. The model is able to simulate most common types of collectors, with up to three transparent covers of any material. Using primarily equations available from the literature the...
A covariant form of Hamilton's Principle of Stationary Action is formulated and used to solve the general eiconal equation describing the wave function of light in a medium carrying ultrasound. Tensor notation is reviewed and the tensor form of...
Mass transit vehicles in formal rail service frequently attain speeds which can excited carbody oscillations (primary hunting), as well as sustained alteral oscillations of the trucks (secondary hunting). The carbody motions have been shown to...
Eddy current inspection methods are used extensively in industry for the nondestructive testing of a wide varity of materials and product applications. The general theory of eddy current inspection is described. Equations defining the depth of...
In this paper the effects of inertia are explored for the case of a thermal excitation applied on the surface of an infinitely long, solid circular cylinder. The linear uncoupled field equations for a homogeneous, isotropic, thermoelastic medium...
A digital computer model has been developed to simulate the kinetic response of a thermal pressurized water reactor power plant. The program is capable of predicting core power and plant temperature variations which result from distrubances due to...
The boundary integral technique was implemented in a computer code for the general static analysis of three dimensional elastic solids. The was based on a formulation of the problem in which the governing boundary equation is developed from the...
A method is presented which permits the measure of nose tip recession of re-entry vehicles and advanced terminal interceptors by employing a double choked flow coolant gas system. Recession of the tip results in an increased exit flow area which...
High-speed operatorless photographic printers require high illumination levels at the negative print gate from lamps with stable color temperatures. The lamps using in these applications give off a large amount of heat radiation that is harmful to...
This research involves design and implementation of computer program for simulation of a wastewater treatment plant. The program has the capability to be interfaced with an existing analog wastewater plant process flow training board which is...
The objective of this study is to develop guidelines for the analysis of storm water retention ponds in Central Florida. Development of a combined seepage analysis considering both unsaturated and saturated groundwater flow incorporation into a...
