Case studies of heat conduction in rotary drums with L-shaped lifters via DEM

Material Flow in Rotary Drums

The experimental investigation of material flow in rotary drums is studied. An equipment in the size of pilot-scale was used to collect experimental data for investigation of validity of the conventional steady-state model of material flow in rotary drums. Also, the transient data of the time required for material movement in the empty drum up to any specified cross section are also reported. T...

Analysis of Heat Penetration into the Solid Bed of Rotary Drums

The heat penetration into the solid bed of rotary drums was experimentally investigated. An indirect heated rotary drum with a diameter of D=600 mm and a length L=450 mm has been used for this purpose. Temperature profiles of the gas, the drum wall and the solid bed were measured using 16 Type K thermocouples assembled on both a rotating and a fixed rod that attached inside the drum. Hence, the...

Longitudinal Conduction in Cross Flow Heat Exchanger with Condensation

The deterioration of the performance of a cross flow heat exchanger with condensation due to the longitudinal conduction was investigated. For a relatively small change of wall temperature along the flow directions which was shown to be common in many applications, the energy equations were solved numerically. An iterative method was used to solve the resulting equations of the finite differenc...
