Convective heat transfer in a rotary kiln

An experimental study of convective heat transfer from hot air to the solid charge and walls in a non‐fired rotary kiln is reported. Ottawa sand was heated by passing it counter‐current to a flow of preheated air in a 2.5 m 0.19 m I.D. rotary kiln. Axial temperature

Accelerated heat transfer simulations using coupled DEM

2019/12/1The EDEM-CFD coupling is employed to simulate heat transfer from the hot gas phase to the particle phase in an aggregate dryer. Moreover, complex industrial applications that involve hundreds of thousands of particles are so computationally expensive that not even the most efficient couplings are able to support.

Accelerated Heat Transfer Simulations Using Coupled CFD

A model of an aggregate drum dryer was used to produce hot mix asphalt and different configurations have been implemented to investigate the effect of GPU-CPU technology in such a complex simulation. Commercial codes from ANSYS and DEM-Solutions were coupled to simulate heat transfer from the hot gases to the aggregate particles.
