试验结果表明:孔隙度和渗透率随压密压强的增大近似呈线性减小;渗透率随孔隙度增加,呈近似线性增加.此研究为粮堆机械通风冷却效果及流动阻力的计算提供了可靠依据.
The results show that the porosity and permeability decrease approximately linearly with the increase of compaction pressure, and the permeability increases linearly with the increase of porosity. This study provides a theoretical basis for the mechanical ventilation cooling effect and flow resistance calculation Reliable basis.
