(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 11: The axial thrust is basically generated by a pressure imbalance across the impeller. The impeller is subjected to a great force trying to move it against the incoming flow. The cumulative thrust of all impellers ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 5: It is important that gas turbines used in Oil & Gas applications can burn a wide variety of fuels with the minimum impact on the environment or economics. Many types of gaseous and liquid fuels that can be used ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Condition monitoring is one of the critical process in turbomachinery equipment. As a factory equipment, Turbormachinery mostly transfers data via controllers such as programmable-logic-controller (PLC). Parameters of the ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 17: The various drivers for process compressor trains are designed in accordance with the pertinent process requirements. In the case of variable speed applications for process compressors, Steam turbines or Gas ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 10B: The effects of gas molecular weight variation on a centrifugal compressor’s surge line and computation of the operating margin from surge for the purposes of antisurge control is discussed using different ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 10A: Centrifugal compressors are subject to transient events, such as emergency shutdowns, which can cause energetic surge events during rapid shutdown transients. Many modeling tools are used to predict the ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 10C: This tutorial discusses the design and function of surge control systems, or more precisely, surge avoidance systems on the basis of the behavior of centrifugal compressors when they interact with compression ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This paper discusses the development of Actuators over a period of time. The purpose of an Actuator (servo system) is to operate steam turbine control valves. With the increasing demand for better control of steam valves ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)A major U.S. pipeline company was experiencing multiple problems at a crude pipeline intermediate pump station. The application seemed ideal for a rotary positive displacement (PD) pump. Working with a vendor and seeing a ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)A 1970 vintage polyethylene plant faced a market driven requirement to improve its polyethylene grade. The improved, new grade required a new highly reactive catalyst and needed to be ready for customer’s product trial in ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Failure of an industrial scale bevel gear assemble in 2.5 years of its commissioning. The gear box drives a pumps rated at 16240m3/h at 47.5 meter of head. The unit developed an abnormal noise with slightly higher impacting ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 13: This paper deals with the damping ratio D (modal damping) of the 1st torsional mode of synchronous motor driven compressor trains. The damping ratio is a crucial parameter for the torsional start-up analysis ...
