Mixing and heat transfer of binary mixtures of ... - ScienceDirect

The results indicate that, depending on the physical parameters and thermal properties of particles, the mixing quality does not always accurately reflect the heat transfer effect. In binary granular beds of monodispersed spherical particles with different densities and thermal diffusivities, the main heat transfer mechanism is related to the ...

Influence of baffles on mixing and heat transfer

Jan 01, 2022  Effect of baffles on mixing and heat transfer in drums is studied by DEM. • The optimal length-to-diameter ratio of central baffles varies in a range of 0.4–0.7. • The traditional short peripheral baffle slightly deteriorates mixing and heat transfer. • The peripheral baffles perform best at high length-to-radius ratio of 0.9. •

CFD-DEM modelling of mixing and segregation of binary mixtures

Jan 24, 2019  Solid-liquid fluidized beds of binary mixtures are widely used in many industries. Particle segregation may occur as particles can differ in size, density, or shape. Extensive studies have been conducted in the past to understand the effects of particlesize and density on the mixing and segregation, but the effect of particle shape has not been well addressed.

Enthalpy of mixing - Wikipedia

The enthalpy of mixing (or heat of mixing or excess enthalpy) is the enthalpy liberated or absorbed from a substance upon mixing. When a substance or compound is combined with any other substance or compound the enthalpy of mixing is the consequence of the new interactions between the two substances or compounds. This enthalpy if released exothermically can in an
