  • Mobilne Laboratorium Diagnostyki i Technologii Środowiska

    Laboratorium Diagnostyki i Technologii Środowiska umożliwia pomiar, analizę i ocenę istniejących oraz nowo opracowanych procesów technologicznych w skali ułamkowo technicznej. Ze względu na złożoność procesów chemicznych i zagadnień związanych z ochroną środowiska często występuje konieczność prowadzenia badań w miejscu powstawania odpadów lub prowadzenia procesu produkcyjnego. Z tego powodu zaprojektowano i wykonano instalację...

  • Signals features extraction in radioisotope liquid-gas flow measurements using wavelet analysis

    Publication

    - EPJ Web of Conferences - Year 2019

    Knowledge of the structure of a flow is significant for the proper conduct of a number of industrial processes. In this case, a description of a two-phase flow regimes is possible by use of the time-series analysis in time, frequency and state-space domain. In this article the Discrete Wavelet Transform (DWT) is applied for analysis of signals obtained for water-air flow using gamma ray absorption. The presented method was illustrated...

  • Radioisotope measurements of the liquid-gas flow in the horizontal pipeline using phase method

    Publication

    - EPJ Web of Conferences - Year 2018

    The paper presents application of the gamma-absorption method to a two-phase liquid-gas flow investigation in a horizontal pipeline. The water-air mixture was examined by a set of two Am-241 radioactive sources and two NaI(Tl) scintillation probes. For analysis of the electrical signals obtained from detectors the cross-spectral density function (CSDF) was applied. Results of the gas phase average velocity measurements for CSDF...

  • Analysis and interpretation of radiometric signals in a liquid-gas bubble flow

    Publication

    - EPJ Web of Conferences - Year 2019

    The article presents the analysis of signals from a radiometric system consisting of two scintillation probes and two gamma radiation sealed sources. Calculations and interpretation were carried out for the bubble flow of the water-air mixture in the horizontal pipeline. The analysis of the obtained signals was done in time and frequency domain. In the frequency domain, a range of usable frequencies was identified, which were associated...

    - EPJ Web of Conferences - Year 2018

    The rapid development of tomography methods particularly electrical, X and gamma rays allows for a wide range of the information about flow structure. However, all of such methods are quite complicated. At the same time much simpler systems as the measuring system of gamma rays absorption, allows to obtain a all key flow information which describe the two-phase flow. In the article the results of analyzes of radiometric signal...
