A method for the spatial dynamic simulation of reciprocating compressors using the digital computer
(Virginia Polytechnic Institute and State University, 1987)
This thesis introduces the application of computer-aided engineering techniques to the dynamic analysis of reciprocating compressor designs. The analysis process is detailed in three steps.
The first step, an interactive ...
Dynamic simulation of solar calibration of the total, Earth- viewing channel of the Earth Radiation Budget Experiment (ERBE)
(Virginia Polytechnic Institute and State University, 1987)
The Earth Radiation Budget Experiment (ERBE) is an operational system of radiometric instruments placed in Earth orbit by the National Aeronautics and Space Administration (NASA). Its purpose is to monitor those components ...
A study of tip-leakage flow through orifice investigations
(Virginia Tech, 1987-10-05)
"Compressible fluid dynamics of flow through plain-faced long orifices was investigated with the hope of gaining insight into the fluid dynamics of tip leakage flow. The Reynolds number range investigated was greater than ...
Structural shape optimization of three dimensional finite element models
(Virginia Tech, 1987-08-26)
<p>The thesis presents a three dimensional shape optimization program which analyzes
models made up of linear isoparametric elements. The goal of the program is to achieve
a near uniform model stress state and thereby ...
Analytical method for turbine blade temperature mapping to estimate a pyrometer input signal
(Virginia Tech, 1987-05-05)
<p>The purpose of this thesis is to develop a method to estimate local blade
temperatures in a gas turbine for comparison with the output signal of an experimental
pyrometer. The goal of the method is to provide a ...
Development of a data reduction method for a high frequency angle probe
(Virginia Tech, 1987-03-15)
<p>A data reduction method has been developed and tested for a high frequency angle
probe. The angle probe is designed for unsteady aerodynamic measurements in
transonic cryogenic wind tunnels. The probe measures ...
A personal computer based instrumentation system for determining real-time dynamic torque in rotating machinery
(Virginia Tech, 1987-06-10)
<p>Measurement of dynamic/transient torques is important in the dynamic analysis of rotating
machinery as it provides insight into the internal state of the machine. Existing methods are
difficult to implement, results ...
Application of the finite element method in high-side gondola rail car design
(Virginia Tech, 1987-10-14)
<p>Finite element models of four design configurations of a proposed composite
aluminum-steel high-side coal gondola rail car were developed. The designs were analyzed
for compliance with the loadings set forth by the ...
A finite element study of bending stress variation in meshed spur gear pairs
(Virginia Polytechnic Institute and State University, 1987)
A study of the bending stresses in a pair of meshed spur gears using the finite element method is presented. The models analyzed were in the shape of a circular gear with five teeth or a five-tooth rack. A unit torque (1 ...
Tip leakage flow, heat transfer and blade lifting in a jet engine turbine
(Virginia Polytechnic Institute and State University, 1987)
An existing Navier-Stokes code (MEFP) was used to calculate developing flow and heat transfer in turbine tip gaps. Successful calculations of the heat transfer to a model turbine blade tip were obtained with a Prandtl ...
