Simulation of Heat Transfer of Horizontal and Vertical Cooling Ventilation in Warehouse

Abstract

Through the analysis of the temperature front, the paper compared different ventilation methods. It is very important for economic and safe grain storage. The paper simulated the horizontal ventilation and vertical ventilation process in warehouse by computational fluid dynamics method. It showed horizontal ventilation and vertical ventilation temperature chart. This paper discusses the distribution of the temperature in the granary. The numerical results were validated by comparing them with related data. The simulation results showed that the velocity of the transverse cooling front is faster than that of the vertical ventilation. The cooling rate and the cooling efficiency of lateral ventilation is higher than that of the vertical ventilation. The paper provides a theoretical basis for the operation and management of stored grain ventilation in the future.
