-
(Texas A&M University. Turbomachinery Laboratories, 2012)A centrifugal compressor presenting rotating stall can exhibit many problems, as limitation on its operational range, high level of subsynchronous vibrations, reduced efficiency and premature bearing wear. There are many ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)Condenser cooling water flow requirements for large turbine-generator sets are controlled both by the thermal input range of the turbine and the variety of climatic conditions affecting the cooling tower. The resulting ...

(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)Charts relating the efficiency of a single stage centrifugal pump to the specific speed were presented at the Texas A&M University Third International Pump Symposium in April 1986 [1]. These charts attempted to resolve ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Rotating machinery relies on engineered tilting-pad journal bearings (TPJB) to provide static load support with minimal drag power losses, relatively low pad temperatures, and ensuring a rotor dynamic stable operation. End ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Understand the interaction between the gas required to lubricate the seal and the effect of the gas on pump performance.
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)The effect of rotor mechanical unbalance on pump vibrations was tested for a typical ANSI pump. It was found that significant damping of vibrations occurs at actual (wet) operations as compared to dry run. Rotor forces and ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)The lecture presents measurements of the static and dynamic load performance conducted with a tilting pad journal bearing running under flooded and evacuated conditions and lubricated with flow rates ranging from a nominal ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)High pressure compressors are commonly equipped with honeycomb seal on the balance piston, as an effective mean to improve the rotordynamic stability of the system. The gas leakage flow across the honeycomb seal clearance ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)A chart relating the efficiency of centrifugal pumps to the specific speed and capacity at the maximum efficiency capacity has been in use in the pump industry for almost forty years. While it has been useful to both the ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)A new 46 MW steam turbine became unstable as the load on the turbine was increased. The turbine had a relatively long slender shaft and the subsynchronous frequency was near the first critical speed of 1800 rpm. In an ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)This case study is concerned with effect of the swirl canceller for impeller excitation force of integrally geared compressor. The 5th stage shaft vibration of booster air compressor showed abnormal behavior as the discharge ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)This work shows the effect of an Off-line wash system with water based on the case of 3 gas turbines Ruston TB5000 located in high polluted conditions like ashes in the ambient, high humidity and temperature. This research ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)Three vertical pumps at a wastewater transfer station a few miles away from the San Andreas Fault and next to an apartment building were the source of vibration and noise complaints. To attune the transmitted vibration, a ...
-
(Texas A&M University. Turbomachinery Laboratories, 2012)Following the changes to API 671, there is a requirement to reduce temperature around guarded coupling designs. Existing features used in high performance (HP) couplings involve various methods of shrouding and covering ...
-
(Texas A&M University. Turbomachinery Laboratories, 2006)This paper describes the steps performed by the authors’ company to validate and qualify the introduction of a new fire protection system for heavy-duty gas turbines based on water mist technology. Initially, a finite ...
