  - Rok 2018

  The main aim of the following paper is mathematical modelling for momentum, heat and mass transfer, which is accompanied by chemical surface reactions of the flow of the mixture helium and methanol. The thermocatalytic devices used for decomposition of hydrocarbons incorporate vertical microchannels coupling at the ends and heated to 500 oC at the walls. The results of the experiment were compared with CFD calculations to calibrate...

  The main goal of the following work is to adjust mathematical modelling for mass transfer, to specific conditions resulting from presence of chemical surface reactions in the flow of the mixture consisting of helium and methanol. The thermocatalytic devices used for decomposition of organic compounds incorporate microchannels coupled at the ends and heated to 500 oC at the walls regions. The results of the experiment were compared...

  - TASK Quarterly - Rok 2018

  Numerical modelling of hydrogen production by means of methanol decomposition in a thermocatalytic reactor using corrugated foil made of the Ni3Al intermetallic phase is shown in the paper. Experimental results of the flow analysis of mixtures containing helium and methanol in a thermocatalytic reactor with microchannels were used for the initial calibration of the CFD calculations (calculations based on the Computational Fluid...

  - Acta Energetica - Rok 2017

  The article presents the problem of protection of earthing reactors connected to the star point of shunt reactors in high voltage lines, with particular regard to the detection of internal faults. Model analyses for an actual system commissioned in 2015, which is intended to be provided with earthing reactors, are included.

  • Z. Lubośny
  • J. Klucznik
  • S. Czapp

  - Rok 2017

  The IEEE and CIGRE recommend protection systems for high voltage shunt reactors. Unfortunately the recommendations do not include guidelines for the protection of neutral earthing reactors, which are often connected to shunt reactors to increase the effectiveness of single pole auto-reclosing. The paper discusses earthing reactor protection issues with particular emphasis on the detection of internal faults. An analysis carried...

  • R. Aranowski

  - Physicochemical Problems of Mineral Processing - Rok 2017

  Spinning fluids reactor (SFR) is one of the most efficient gas-liquid contacting system with high potential of application in many fields. The unique solution of SFR is the contacting of two spinning fluids which generated centrifugal force. The aim of this study was to investigate the pressure field distribution on the inner surface of reactors dispersing element. Obtained results confirm the high heterogeneity of the field pressure...

  • M. Skuza

  - Rok 2004

  Przy projektowaniu reaktorów z reguły stosuje się model przepływu tłokowego - prosty, lecz mało dokładny. W pracy pokazano wpływ dokładności stosowanej metody opisu pola prędkości na poziom projektu reaktora.

• Hydraulic and technological consequences of reactor asymmetry

  Publikacja

  • J. Sawicki

  - Rok 2005

  Każdy reaktor, choć projektowany jako obiekt o regularnych kształtach, może utracić symetrię - bądź wskutek błędów wykonawczych, bądź wskutek odkształceń w trakcie eksploatacji. Fakt ten wpływa na pole prędkości przepływającej cieczy i może mieć znaczące skutki technologiczne. W pracy omówiono metodę określania tych konsekwencji i zilustrowano ją przykładami.
