Gas Turbine Compressor

Characterization of the aerodynamics of the flows within gas turbine intrablade passages requires the development of sensitive laser-Doppler velocimeters, a data acquisition system capable of efficiently and accurately handling substantial quantities of data, and appropriate methods of posttest data analysis and display to maximize the value of the recorded data. Pratt & Whitney developed a confocal LDV and data acquisition system that were first employed in the mid-1970s for gas turbine intrablade fan studies. Experience gained through use of the instruments in several aerodynamic studies has provided the basis for the development of a second generation system. The performance of the recently enhanced instrument configured as a single-component LDV has been demonstrated by a NASA-sponsored fan study in which approximately 200 million valid velocity signals were rapidly acquired. The high resolution and data rates achieved permitted detailed mappings of the flow at a variety of conditions and locations. Following this successful study, a second NASA-sponsored program was initiated to assess the feasibility of utilizing this LDV capability to perform detailed stator–rotor interaction studies in a multistage compressor. The equipment employed in these studies will be described and data typical of the findings will be presented.

Pebble Bed

A full-scale heat transfer test facility has been designed and built for the determination of effective thermal conductivity of pebble bed, which is a macroscopic parameter to characterize the heat transfer capacity of the core in the High Temperature Gas-Cooled Reactor. The data acquisition system is developed to collect, display and record the temperature data in monitoring points. Two alternative software systems are designed to obtain better performance. To enhance precision of the measurement system, several aspects are analyzed and optimized in the implementation of LabVIEW. The error of the hardware system is analyzed, which is within the acceptable range. The data acquisition system can meet the practical demands of temperature acquisition in the range of thermal analysis.

Significant Cost Reduction

A powerful, low cost, gas turbine data acquisition system capable of handling 24 or more channels of high and low level data is now in use at the University of Tulsa. The assembled system hardware, less transducers, is priced at about six thousand dollars and shows potential for further significant cost reduction. Easily programmed in the BASIC language, the microcomputer commands an analog-multiplexing digital voltmeter, decodes the resulting serial data, and performs conversion to engineering units. It also processes data for display on a color television monitor, for storage on diskette, and for transcription on a printer. Examples, showing gas turbine performance, clearly portray the power of the general purpose microcomputer in an engineering data acquisition system and its potential for engineering education.
