Gas-dynamic Analyzer of Nitrogen-hydrogen Mixture for Industrial Application
Journal Title: Energy Engineering and Control Systems - Year 2015, Vol 1, Issue 2
Abstract
Mathematical model of gas-dynamic analyzer of nitrogen-hydrogen mixture built on bridge throttle scheme using laminar-turbulent and turbulent-laminar throttle dividers is developed in the paper. The developed analyzer has twice higher sensitivity than any of these dividers. The authors developed the algorithms for calculation the constructive parameters of gas-dynamic analyzer of nitrogen-hydrogen mixture to provide optimal sensitivity of the throttle bridge scheme. The types of throttle elements have been selected, their dimensions have been calculated, technical means for realization of gas analyzer scheme have been proposed. The authors developed a principal scheme of the gas analyzer of nitrogen-hydrogen mixture and calculated its static characteristic. The influence of uninformative parameters such as temperature and pressure of nitrogen-hydrogen mixture on output signal of analyzer is analyzed and measures for their stabilization are proposed. The authors also proposed tasks for the experimental investigation of the developed gas-dynamic analyzer.
