Abstract: By enhancing the uniformity of the temperature and velocity fields’ distribution in curing barn, the quality of flue-cured tobacco effectively can be improved, and the curing time can be shortened to some degree, therefore, the energy consumption of curing can be reduced. Taking the standard bulk curing barn as the investigated subject, the model of air flow in curing barn with k-ε three-dimension two equations turbulent flow was established. Based on the large software of Fluent within computation fluid dynamics, the numerical simulation of the temperature and velocity distribution in curing barn was conducted in detail. The reasonable supply air volume for bulk curing barn was obtained. The results of numerical simulation could be used for the structure design of bulk curing barn, the temperature and velocity distribution optimization and the selection of circulation fan.
