Predicting the drop size distribution (DSD) is essential in particulate flows such as emulsions as it affects mass transfer and heat transfer. In the current work we developed a novel numerical method to account for droplet ...

The paper presents the extension of the GENTOP model for phase transfer and discusses the sub-models used. Boiling flow inside a wall heated vertical pipe is simulated by a multi-field CFD approach. Sub-cooled water ...

In the present work we analyse applicability of the adaptive multiple size-group (A-MuSiG) population balance method to modelling of multiphase flows. The dispersed phase is split into M size-groups, each one having its ...

The work presents a comparison of catalytic gas-solid reactions in a packed bed as simulated on two widely different scales: direct numerical simulation (capable of accurately predicting transfer phenomena in and around a ...

Experiments and numerical conjugate heat transfer simulations are performed on a simple T-pipe geometry. The T-pipe geometry is partially insulated and mimics subsea equipment which is subject to cool-down after a production ...

In this paper, an efficient ghost-cell based immersed boundary method is introduced to perform direct numerical simulation (DNS) of particulate flows. The fluid-solid coupling is achieved by implicit incorporation of the ...

Due to the increase in the oil prices and the depletion of the oil reserves, Fischer-Tropsch processes for the production of synthetic fuels, methanol synthesis and other gas-to-liquid processes are rapidly gaining interest. ...

In industry we encounter many processes that rely on equipment in which particles are suspended by a gas flow, such as pneumatic conveyors, CFB gasifiers, combustors and fluidized bed reactors. In numerical models of these ...

Conventional pressure based flow distributors face challenges in the form of operational limits as their low outlet density and non-uniform flow distribution path, often act as bottleneck in the overall chemical equipment ...
