It was statement what the porous flow in grain bulks, its movement ways, influence factors and relationship with grain store are. The porous flow of the grain bulks is caused by the temperature and pressure different. It moves in three lines: convection between inside and outside the bulks, convection inside the bulks, and convection between inside and outside the storehouse. It is influenced by the temperature different, the grain bulks seal condition, the clearance between grain particles, the style of store house, and the grain storage ways, and so on. Used ways of the porous flow in the gr...
