An experimental study of lifting and moving forces in air conveying systems
(Virginia Tech, 1992-02-04)
Development of an infrared gaseous radiation band model based on NASA SP-3080 for computational fluid dynamic code validation applications
(Virginia Tech, 1992-08-01)
The increased use of infrared imaging as a flow visualization technique and as a validation technique for computational fluid dynamics (CFD) codes has led to an in-depth study of infrared band models. The ability to create ...
A numerical study of equivalence in scanning thermistor bolometer radiometers for earth radiation budget applications
(Virginia Tech, 1993-02-05)
The Earth Radiation Budget Experiment (ERBE) consists of a suite of three scanning and four nonscanning radiometric instruments on each of three satellites which monitor the solar-reflected and Earth-emitted components of ...
Dynamic Electrothermal Model of a Sputtered Thermopile Thermal Radiation Detector for Earth Radiation Budget Applications
(Virginia Tech, 1997-08-28)
The Clouds and the Earth's Radiant Energy System (CERES) is a program sponsored by the National Aeronautics and Space Administration (NASA) aimed at evaluating the global energy balance. Current scanning radiometers used ...
Prediction and Measurement of Thermal Exchanges within Pyranometers
(Virginia Tech, 1999-10-28)
The Eppley Precision Spectral Pyranometer (PSP) is a shortwave radiometer that is widely used in global networks to monitor solar irradiances at the earth's surface. Within the instrument, a blackened surface is in intimate ...
Simulation of an algorithm for the active control of combustion noise
(Virginia Tech, 1990-12-16)
The simulation of an algorithm for the active control of combustion noise generated by a turbulent flame produced by an open burner is developed in this thesis. The simulation includes (1) an autoregressive model of real ...
A numerical study of cylindrical electric furnace performance using the finite element method
(Virginia Tech, 1996-02-15)
<p>Described is a development of a new finite element-method-based numerical technique to carry out the steady-state thermal analysis of a cylindrical electric furnace. Such furnaces are in common use for the continuous ...
A turbulent combustion noise model
(Virginia Tech, 1989-05-05)
