Development of Graphical Indices for Building Energy Data
(Texas A&M University, 1993)
Graphs are an effective and efficient way of displaying quantitative and statistical information. Unfortunately, only a few studies have systematically looked at presenting data in forms which are both informative and easy ...
An Improved Procedure for Developing a Calibrated Hourly Simulation Model of an Electrically Heated and Cooled Commercial Building
(Texas A&M University, 1994)
With the increased use of building energy simulation programs, calibration of simulated data to measured data has been recognized as an important factor in substantiating how well the model fits a real building. Model ...
The effect of periodic unsteady wakes on boundary layer transition and heat transfer on a curved plate
(Texas A&M University, 1996)
The effect of unsteady periodic wakes on heat transfer and boundary layer transition was investigated on a constant curvature heat transfer curved plate in a subsonic wind tunnel facility. The local heat transfer coefficient ...
Rehabilitating missing energy use and weather data when determining retrofit energy savings in commercial buildings
(Texas A&M University, 1999)
This thesis evaluates four methods for rehabilitating short periods of missing data. Single variable regression, polynomial models, Lagrange interpolation, and linear interpolation models are developed, demonstrated, and ...
A new three-control-volume theory for circumferentially-grooved liquid seals
(Texas A&M University, 1994)
Circumferentially-grooved seals are used in centrifugal pumps to reduce leakage flow. Florjancic (1990) developed an analysis using a partition of the seal into three control volumes, bulk-flow theory and Hirs' lubrication ...
Design methodology for tracking certain and uncertain non-minimum phase systems
(Texas A&M University, 1997)
A design methodology is developed for obtaining tracking controllers for non-minimum phase systems. The discussion centers around a solution for the error equation E(s) = [1- H(s)] Yd(S)'Tracking error is eliminated by ...
Continuous equal channel angular extrusion of glassy polymers
(Texas A&M University, 1997)
This thesis presents an analysis of Equal Channel Angular Extrusion (ECAE) of polymers, a unique process that controls the state of strain and molecular network orientation during a solid state extrusion. The goal of this ...
Development and application of a procedure to estimate overall building and ventilation parameters from monitored commercial building energy use
(Texas A&M University, 1997)
This thesis proposes and validates a simplified model appropriate for parameter identification and evaluates several different inverse parameter identification schemes suitable for use when heating and cooling data from a ...
Effects of the primary passage on the flow through the secondary passage of a shrouded-impeller pump
(Texas A&M University, 1994)
A method for determining the turbulent flow through the leakage passage in rotating machinery has been enhanced to allow for the modeling of complex multiplyconnected flow domains such as that of the combined primary and ...
Effect of additives on the reduction of nitrogen oxides using cyanuric acid
(Texas A&M University, 1994)
The addition of cyanuric acid to hot exhaust flows has been shown in the past to selectively remove much of the nitric oxide (NO) emitted from combustion sources. Known as the RapreNOx process, this approach to pollution ...
