An Experimental Study on the Effects of an Upstream Gate Valve on the Accuracy of an Insertion Type Flowmeter
(Texas A&M University, 2003)
Flowmeters measure the consumption of chilled water or hot water in buildings. Depending on the accuracy, cost consideration, and available space, the flowmeter selected could be an insertion type or fixed type such as ...
Modeling of air brakes for onboard diagnostics of heavy trucks
(Texas A&M University, 2000)
Accidents involving commercial vehicles have disastrous consequences; most of the times they result in human fatalities, environmental damage, traffic congestion leading to fuel wastage and associated productivity losses. ...
An experimental investigation into oil mist lubrication
(Texas A&M University, 2000)
Oil mist lubrication offers many advantages over sump lubrication. Unfortunately, mist lubrication generates sub-micrometer sized aerosol particles (fines) that escape from the oil mist lubrication system. These particles ...
Improving the searching abilities of a real-valued genetic algorithm
(Texas A&M University, 2000)
This investigation shows that a genetic algorithm seems to be able to search a solution space more effectively with the addition of a gradient-based local improvement scheme. The objective of this research was to determine ...
Rotordynamic evaluation of frequency dependent impedances of hole-pattern gas damper seals
(Texas A&M University, 2000)
Two hole-pattern seals are compared with one smooth bore seal. The two hole-pattern seals have cell depths of 2.03 mm and 3.18 mm with a cell diameter of 1.59 mm. The hole area density factor for both hole-pattern seals ...
Evaluation of a slotted orifice plate flow meter using horizontal two phase flow
(Texas A&M University, 2000)
In the past several years, the slotted orifice plate has been evaluated for its performance as a single phase flow meter using air and as a two-phase flow meter using water and air. These previous studies have both shown ...
Evaluation of Mixing Downstream of Tees in Duct Systems with Respect to Single Point Representative Air Sampling
(Texas A&M University, 2003)
Air duct systems in nuclear facilities must meet the requirements of ANSI N13.1-1999 and the Environmental Protection Agency (EPA) that the exhaust airflow be monitored with continuous sampling in case of an accidental ...
Numerical simulation of micro-fluidic passive and active mixers
(Texas A&M University, 2002)
Numerical simulations of mixing using passive and active techniques are performed. For passive mixing, numerical modeling of a micro-fluidic device, build by Holden and Cremer, was performed. The micro-fluidic device ...
Turbulent heat transfer in rotating rectangular cooling channels with angled ribs and dimples
(Texas A&M University, 2001)
An investigation into determining the effect of rotation on heat transfer in smooth, rib-roughened, and dimpled rectangular channels with aspect ratio of 4:1 is detailed in this thesis. Internal cooling channels are ...
Buckling and vibration of orthotropic plates with an internal line hinge
(Texas A&M University, 2001)
This study presents analytical solutions for the buckling and vibration of uniaxially/biaxially loaded orthotropic thin and thick rectangular plates with an internal line hinge. The plate is taken to be flat, rectangular, ...
