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 ...
-
Cable, Travis Alexander (2015-07-15)Integrally geared compressors (IGCs) comprise of single stage impellers installed on the ends of pinion shafts, all driven by a main bull gear (BG) and shaft system. When compared to single shaft multistage centrifugal ...

San Andres, Luis; Delgado, Adolfo (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...

Gaurav, (2009-05-15)A low speed wind tunnel experimental investigation was conducted to determine the effectiveness of the leading edge pulsed blowing and the trailing edge jet blowing/ Gurney flap on the improvement of aerodynamic performance ...
-
Khan, Rehan (2014-04-24)A study is presented to develop framework for correlating sand strength (friction angle) to geophysical measurements, primarily shear wave and body wave velocities. Triaxial tests accompanied by wave velocity measurements ...
-
San Andres, Luis; Lubell, Daniel (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The short course provides practicing engineers with a comprehensive review of existing gas bearing technologies including their principle of operation, analysis and experimental verification, comparison amongst other gas ...

Ramakrishnan, Vijay (Texas A&M University, 2004-09-30)This thesis presents the development of calibration and data-reduction algorithms for non-conventional multi-hole pressure probes. The algorithms that have been developed for conventional 5- and 7-hole probes are not optimal ...
-
Li, Yingkun (2015-07-17)Tilting pad journal bearings (TPJBs) supporting rotors for high performance turbomachinery have undergone steady design improvements to satisfy more stringent operating conditions that include large specific loads due to ...
-
Song, Ju Ho (2009-06-02)A new foil bearing with compression springs is designed, built, analyzed, and tested. This foil gas bearing uses a series of compression springs as a compliant structure instead of corrugated bump foils. A spring model to ...
