Modelling gas-solid two-phase flows using a two-fluid approach has two main difficulties: formulating constitutive laws for the particulate stresses and modelling the gas turbulence modulation. Due to the complex nature of the gas-particle interactions, there is no universal model covering every flow...
Gas-solid flows are involved in numerous industrial processes and occur in various natural phenomena. This authoritative book addresses the fundamental principles that govern gas-solid flows and the application of these principles to various gas-solid flow systems. The book is arranged in two parts:...
A revised cluster diameter correlation, which is based upon the analysis on added mass force in heterogeneous gas–solid flows, is then proposed for revising the EMMS model. The EMMS model thus improved is incorporated into an Eulerian description of gas–solid flow as a sub-grid scale model ...
practical issues are scattered within the text and sometimes hidden amongst the mathematics and transport phenomena which make the outcomes of the surface reaction(s) so dif®cult to explain and interpret. However, anyone who has mastered the basic theory but is struggling to evaluate or optimize...
The paper presents a review of theoretical and experimental works devoted to two-phase (gas-solid) flows past bodies. The particularities of particle motio
Turbulence enhancement by particle wake effect is studied by numerical simulation of gas turbulent flows passing over particle under various particle sizes,inlet gas velocities,gas viscosity,gas density and the distance of particles.By performing dimension analysis and using the form of gas-particle inte...

Gas–solid flows and wall erosion of the modified vortex elbow are studied by the combined approach of discrete element model for particles and computational fluid dynamics for the gas phase. The validity of the model is first examined by comparing the predicted pressure drop and wall erosion ...
