  • This book presents the papers given at a conference on the use of measuring instruments in energy applications. Topics considered at the conference included instrumentation for the measurement of two-phase flows in gas turbine engines, laser doppler velocimeter signal quality in a spark ignition engine, measurements of flow from a fuel nozzle, anemometers for loss of coolant measurements, two-phase flow in pipelines, flame propagation, shock wave-turbulent boundary layer interaction, and open-channel flow.
  • In order to improve the operational behavior (efficiency and stability) of the cyclone separator system in Escatron PFBC power plant, a laboratory-scale cold model has been built. Scaling laws have been applied to simulate the hydrodynamics and performance of the systems, in order to obtain valuable and relevant results for commercial PFBC technology. It has been demonstrated that the filtration effect of the cyclones in a PFBC power plant is extended down to the dipleg. Previous studies in a laboratory-scale cold model have pointed out the importance of the vortex inside the dipleg and its influence in the separation efficiency.more » It is due to the fact that the cyclone effect is still active in the dipleg. These studies are based in pressure drop dipleg measurements. Thermal anemometry has been used to measure the gas velocity and turbulence of several installations. In this case it has been used in order to check the vortex activity in the upper section of the dipleg of a cyclone separator system for a PFBC power plant. This paper deals with the results and conclusions of the research about the velocity field inside the dipleg. The possibility of improving cyclone efficiency by means of extending the vortex, the study of the variables affecting the vortex (and also the cyclone efficiency) and the establishment of a flow-pattern in the dipleg are the main objectives of the research and the paper.« less
  • A method has been developed for determining the magnitude and direction of an unknown velocity vector utilizing two-dimensional thermal anemometry. Unlike most thermal anemometry procedures, the analysis accounts for the velocity component parellel to the sensing element. The method requires determination or calibration of the flow constants at only two flow orientations: perpendicular to each sensing element. A comparison of the analysis to calibrated nozzel flow data showed good agreement for both the flow angle and velocity magnitude within the range of applicability. This type of thermal anemometry will be used to help characterize flows in and around optical accessmore » ports. 2 refs., 1 fig., 1 tab.« less
