Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

The need for clean and environmental friendly fuels is leading the world to the production of
biofuels and replacing conventional fuels by them. Second generation biofuels derived from …

A new computational fluid-dynamic (CFD) model with a separate granular temperature (2/3
random particle kinetic energy per unit of mass) equation for each phase or particle size was …

Positron emission particle tracking (PEPT) is a technique which allows the high-resolution,
three-dimensional imaging of particulate and multiphase systems, including systems which …

The field of multiphase flows has grown by leaps and bounds in the last thirty years and is
now regarded as a major discipline. Engineering applications, products and processes with …

Most of today's computational fluid dynamics (CFD) calculations for gas–solid flows are
carried out assuming that the solid phase is monodispersed, whereas it is well known that in …

A multi-fluid Eularian CFD model with closure relationships according to the kinetic theory of
granular flow has been applied to study the motions of particles in the gas bubbling fluidized …

It has long been known that fluidization of dissimilar materials can result in either a well-
mixed bed or a segregated bed. In a fluidized bed, particle mixing and segregation …

In this study, a gas–solid fluidized bed reactor has been simulated applying CFD techniques
in order to investigate hydrodynamic and heat transfer phenomena. Reactor model …

In many industrial-scale fluidized-bed reactors, particle mixing and segregation play an
important role in determining reactor performance. Detailed information about the particle …
