Mass and heat transfer modelling of soil in screw heat exchangers using CFD Universiteit Gent
Screw heat exchangers can be used for the heating of loose soil with the purpose of disinfecting it. This allows the residual soil on crops to be returned to the field after being taken along during harvest. The primary mode of heat transfer inside a screw heat exchanger is direct contact of soil particles with the heated walls. Rigorous mixing of the soil, induced by the screw’s motion, should increase the number of particles that come into ...
