Zamani Mehrian, Shahla (2021-06-03)An oblique, Cartesian, coordinate system arises from the geometry affiliated with a Gram-Schmidt (QR) factorization of the deformation gradient F, wherein Q is a proper orthogonal matrix and R is an upper-triangular matrix. ...
-
Lipham, Robert Samuel (2020-09-25)An approach for self-sensing is proposed for voice-coil actuators that have an invertible, position-dependent inductance. Actuators with these properties are denoted as position-invertible, variable-inductance (PIVI) ...
-
Wysard Soares, Rachel (2019-06-06)Parametric variations occur throughout bridges service life as a result of temperature fluctuations, cracking, localized damage and fatigue. Likewise, bridges parameters are difficult to estimate precisely; implemented ...
-
Yang, Jongin (2020-11-10)The Mixing Coefficient (MC) is an uncertain, assumed parameter for predicting the leading-edge temperature of a pad film domain. The conventional approach, employing an assumed MC has shown limitations for accurately ...
-
Babbar, Yogesh (2015-05-12)Aeroservoelasticity (ASE) is the interdisciplinary study of the interaction of structural, inertial, aerodynamic, and control loads for aircraft systems, and is inherently a nonlinear phenomenon. One of the goals of ASE ...
-
Stancliffe, Devin Aldin (2011-10-21)Though the Aerospace industry is moving towards small satellites and smaller sensor technologies, sensors used for close-proximity operations are generally cost (and often size and power) prohibitive for University-class ...
-
Vistamehr, Arian (2010-10-12)Automotive turbochargers (TCs) increase internal combustion engine power and efficiency in passenger and commercial vehicles. TC rotors are usually supported on floating ring bearings (FRBs) or semi-floating ring bearings ...
-
Avendano Ovalle, Raul David (2011-10-21)Misalignment in turbomachinery has been commonly known to produce twotimes- running-speed (2N) response. This project aimed to investigate the source of the 2N vibration response seen in misaligned vibrating machinery ...
-
Deshpande, Yateendra Balkrishna (2014-12-15)A rotating synchronous electric machine design can be described to its entirety by a combination of 17 to 24 discrete and continuous parameters pertaining the geometry, material selection, and electrical loading. Determining ...
-
Kumar, Dhruv Dileep (2011-10-21)The present work investigates the phenomena of whip and whirl for a rigid rotor contacting at two bearing locations. The idea originated from an anemometer consisting of a rotor with an elastically supported stator undergoing ...
-
Nicks, Jennifer Elizabeth (2011-02-22)The bump at the end of the railway bridge is a result of differential movement between the bridge deck and the approach embankment. The movement can have the form of a bump or a dip. Either defect in the track geometry ...
-
Kim, Eunseok (2016-10-10)Fluid forces acting on the shrouded centrifugal pump/compressor impellers are evaluated using the computational fluid dynamics (CFD) approach. A face-seal impeller is selected to study for predicting the rotordynamic ...
-
Mortazavi, Farzam (2018-10-22)Eccentrically operating turbomachinery components such as impellers and seals are subject to flow induced forces known as rotordynamic forces. Rotordynamic forces can be detrimental to the machine stability and longevity. ...
-
Ahmed, Shehab (2009-05-15)The quest for energy is leading the industry into drilling deeper wells. Typically, a temperature gradient of 1°C/150 ft can be expected, with bottom hole temperatures reaching beyond 200°C in many areas of the world. ...
-
Su, Xu (2018-11-02)The focus of this study was on concentration polarization (CP) and colloidal fouling control in the vibration enhanced reverse osmosis desalination system and the fundamentals of centrifugal reverse osmosis (CRO). A ...
-
Zhang, Xiong (Texas A&M University, 2005-11-01)The coupled and uncoupled consolidation theories for saturated-unsaturated soils have been discussed. A new method for constructing the constitutive surfaces for saturated-unsaturated soils has been proposed. The consolidation ...
-
Villota Cerna, Elizabeth Roxana (2009-05-15)All practical control systems are subject to constraints, namely constraints aris¬ing from the actuator’s limited range and rate capacity (input constraints) or from imposed operational limits on plant variables (output ...
-
Bae, Yoon Hyeok (2013-04-23)In the present study, a numerical simulation tool has been developed for the rotor-floater-tether coupled dynamic analysis of Multiple Unit Floating Offshore Wind Turbine (MUFOWT) in the time domain including aero-blade-tower ...
-
Gu, Haoyuan (2016-12-08)The catenary anchor leg mooring (CALM) system is widely used as an efficient and economic single point mooring system in offshore engineering applications. CALM buoys are often connected to FPSOs with large flowlines for ...
-
Thompson, Adam; Zhai, Tianbo; Palazzolo, Alan; Keshmiri, Amir (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)High temperatures inside coupling guards can cause machinery down time and loss of revenue. As a result, many industries invest significant time and effort trying to reduce heat generation. Windage flanges are a standard ...
