DOE Energy Conversion and Utilization Technology Program: NBS Measurement Technology Project: Quarterly progress report No. 3, July 1-September 30, 1981
There are two objectives of this task. The initial and primary objective is the development of a technique for fast time response gas temperature measurements in high temperature combustion systems. The accurate determination of time-resolved gas temperatures is particularly important. A closed system optical fiber probe has been chosen to measure wide bandwidth gas temperatures more than one thousand degrees higher than the present state of the art methods. The device consists of a single or several layers of temperature sensitive material applied to the tip of a high temperature optical fiber. Microprocessors analyze the complex optical signals generated by the sensors. The program will address the solid state and optical physics of signal generation and sensor construction together with the fluid mechanics and heat transfer elements which describe the response of the sensor to the conditions in continuous combustion systems. The second objective is to supply critical generic background on high temperature thin film devices for use in non-continuous combustion environments. The thin film devices are for application in internal combustion engines on moving parts, such as valves and pistons, where knowledge of surface temperatures and strains will help in the design of efficient engines. They will also find application in gas turbines. The program will supply information on methods of signal generation and construction in practical thin film devices. Solid state and surface physics studies of the films will be undertaken to develop new methods of high temperature strain, temperature, displacement and erosion/corrosion measurement; heat transfer and structural analyses of the films will be used to develop and understand the preferred methods of constructing durable thin film devices. 2 refs., 3 figs.
