Abstract In a pyrolysis reactor, organic polymers from biomass or plastic waste are thermally decomposed into volatile gases, condensable vapours (tar bio-oil) and solid residues (char). Since these products may serve as building blocks for downstream chemical refinement form the basis of bio-derived fuels, is thought to be instrumental in our progress towards circular economy. A reactor consti...

Abstract Despite the wide possibilities of using a cycloidal rotor in form propulsion systems for unmanned aerial vehicles (UAV), propellers sea-going ships, rotors wind turbines or sea river energy converters, there is practically no research on use this solution fan (CRF) HVAC (heat, ventilation & air conditioning) applications. The main features such machine, compared to conventional sol...

Background Coronary atherosclerosis is common at vessel bifurcations. A quantitative approach to measuring blood velocity, vorticity and more complex flow features at bifurcations would enhance the understanding of the mechanisms of atheroma development, and potentially predict vessels at highest risk. The aim of this work was to validate 4D phase contrast (PC) magnetic resonance imaging flow m...

Light alkanes can be converted to more useful chemicals in noble metal coated monoliths at very short contact times. The short-contacttime reactor is described by detailed models for the flow field, chemistry, and their coupling. The partial oxidation of methane to synthesis gas in a rhodium coated monolith is studied numerically as an example. Keyword: reactor modelling, catalytic partial oxid...

Abstract. Numerical investigations of fluid structure interaction between unsteady flow and vibrating liner in a combustion chamber are undertaken. The computational study consist of two approaches. Firstly, a partioned procedure consists of coupling the LES code AVBP for combustion modelling with the FEM code CaluliX for structural dynamic analysis. The CFD code CFX together with the FEM Ansys...
