Special Issue Information

Dear Colleagues,

The International Scientific Conference on Application of Experimental and Numerical Methods in Fluid Mechanics and Energy 2020 (XXII. AENMFME-2020) took place at Hotel Magnólia – Piešťany, Slovakia on 07-09 October 2020. 

The aim of the international conference was to bring together researchers, designers, experimenters, modellers, and numerical analysts from laboratories, industry, and academia working in the field of two-phase and multiphase flow and experimental methods used in the field of fluid mechanics, thermodynamics, and energy. 

The international conference covers all topics in the measurement and calculation of state variables in the fluid flow, modelling, and simulation in fluid mechanics and energy, optimization of flow parameters in thermal and hydraulic machines and systems, the application of the latest knowledge in the field of fluid mechanics and energy in technical practice, flow visualization, measurement of the energy systems and systems, special experimental methods in fluid mechanics and energy, renewable energy, current problems in the energy sector. 

The conference should contribute to the establishment closer contacts, presentations on the latest knowledge, exchange of experience in the application of different experimental methods, preparation and implementation experiments, results processing and numerical simulations of experiments. 

The Special Issue “The Application of Experimental and Numerical Methods in Fluid Mechanics and Energy 2020” aims to include extended papers from the conference. Topics include but are not limited to the following:  

  • Measurement and calculation of state variables in the fluid flow
  • Modelling and simulation in fluid mechanics and energy
  • Optimization of flow parameters in the thermal and hydraulic machines and systems
  • Application of latest developments in the field of fluid mechanics and energy in technical practice
  • Visualization of flow
  • Measurement of energy systems and systems
  • Special experimental methods in fluid mechanics and energy
  • Renewable energy
  • Current problems in the energy

The present article discusses the potential for hydrogen separation using a metal hydride separator, which facilitates the generation of hydrogen contained in syngas following the thermal recovery of wastes. The article provides a detailed description of the separator heat balance using analytical calculations and optimised calculations, and by applying numerical methods. The proposed concept of a separator intended for hydrogen separation from syngas offers a solution to a problem associated with the use of metal hydride alloy powders; in particular, their low thermal conductivity. In order to eliminate big temperature differences in the alloy, a heat transfer intensifier was implemented in the metal hydride alloy volume; the intensifier was made of metal and exhibited high thermal conductivity. For the purpose of comparing the thermal fields, the first stage comprised the creation of a numerical simulation of hydrogen absorption without the use of an intensifier. Subsequently, three different geometries were created for an intensifier intended to remove heat from the metal hydride alloy powder towards the separator cover, and the effects of these three geometries were analysed. The implementation of heat transfer intensifiers into the metal hydride alloy powder improved the heat removal by as much as 43.9% and increased the thermal field homogeneity by 77%. A result of the heat removal optimisation was an increase in the hydrogen absorption kinetics and the efficiency of the separator operation. Full article
