Jet loop reactors are standard multiphase used in chemical, biological and environmental processes. The strong liquid jet provided by a nozzle enforces both internal circulation of gas as well entrainment dispersion the phase. We present one-dimensional compartment model based on momentum balance that describes phase reactor. This considers influence local variations volume fraction circulation...

The present work focuses on investigating the residence time behavior of microparticles in a concurrent downer reactor through experiments and numerical simulations. For simulations, three-dimensional multiphase model was developed using Euler-Lagrange approach. were performed 0.8 m-long steel with gravitational particle injection. effects different operating conditions, e.g., sheath gas veloci...

The electrocatalytic reduction of carbon dioxide (CO2RR) is a crucial technology to develop the decarbonisation strategy for circularity and producing solar fuels substituting fossil fuels. This viewpoint discusses role electrode reactor design as main factor in determining performance CO2RR, at least under reaction conditions relevant industrial scalability, evidencing need overturn current st...

This research focuses on performing multiphase solid/liquid/gas CFD simulations of a UASB reactor in order to obtain validated model that provides clearer understanding the hydrodynamic behaviour three phases reactors. Eulerian–Eulerian, laminar, three-dimensional, are carried out using Fluent 16.2. The liquid phase velocity and flow profile through PIV experiments. A mean difference 8.45% is f...

color metallography is a useful method for characterizing microstructures of steels with multiple phases. in this paper, application of three different color etching techniques for a bainitic-martensitic steel is reported. comparisons between the results showed that 10% na2s2o5 aqueous solution was the best etchant for distinguishing martensite, bainite and ferrite phases. the obtained microgra...

Around the world, research into multiphase flow is performed by scientists with hugely diverse backgrounds: physicists, mathematicians and engineers from mechanical, nuclear, chemical, civil, petroleum, environmental and aerospace disciplines. Multiphase flow models are required to investigate the co-current or counter-current flow of different fluid phases under a wide range of pressure and te...

Flow chemistry studies can sometimes be difficult to reproduce. In this article we provide guidance scientists for experimental details that should considered as part of any organic chemistry-based continuous flow study. A focus is placed on information provided within reported enable experiments more easily and reliably reproduced. Topics covered include reactor components assembly, important ...

Four matrix-phase crystallographic directions of IN718 are investigated by in-situ tensile tests using neutron diffraction. The elastic diffraction constants for all directions measured are compared to theoretical values calculated by the Kröner model. The differences between the microscopic and the macroscopic material response are given. The accumulation of microstrains in the different cryst...
