A bench scale laboratory ozonator was constructed and determined to produce 27 mg O3/hr. A contacting system and experimental procedure was developed to approximate a mass balance of 0, 1, 2, 4, 8 and 16 ppm were applied to raw and magnesium...
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...
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...
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...
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 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...
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...
A simple and powerful new paraxial ray formalism is shown to provide an alternate method for designing Gaussian Beam Resonators. The theory utilizes the Delano yybar diagram approach and is an extensio of the recent work by Shack and Kessler for...
A system of equations modeling a calss of step motors known as the permanent magnet rotor step motor is presented. The model is implemented on a APPLE personal computer in a version of BASIC. Measurements are then made on an existing motor and...
An analytical investigation was attempted of a solar driven free-piston Stirling engine driving a second free-piston Stirling engine as a heat pump. A dynamic model and a thermodynamic model with free convection heat transfer were derived. The...
An overview of a flight simulation system is presented with a discussion of the system components and the interaction between functional units. The functions of each unit in the visual system are described. Specifically, the projectile subsystem...
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...
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...
Every year the average American throws out more and more garbage. In the next five years, it is projected to increase 20-25 percent. This garbage, termed solid waste, is stored, collected, hauled and disposed of in some manner. The objective of...
Given a transfer function for a differential equation model, an approach for obtaining a solution is by way of bilinear transformation. The bilinear transform approach is a numberical integration scheme which gives a discrete approximation to the...
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...
In order to familiarize local women with advanced degree possibilities in engineering and with expanding loal industry, as well as increasing the graduate enrollment in the College of Engineering, the Univeristy of Central Florida has developed a...
In the design of an elastic structure, a major consideration is the overall stability of the system under axial load or a combination of an axial load and bending moment. In first-order analysis the effects of axial forces on the stiffness...
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...
