【摘要】 在空气、水和小的固体玻璃或氧化铝球形颗粒床层中,测定了两相并流时压降和持液量。测定了流体流率、颗粒粒度及材质,分别对压降和持液量的影响,比较了大颗粒和小颗粒的特性,探计了前人的一些关联式,取得了满意结果。更多还原

【Abstract】 The pressure drop and holdup under two phases and parallel flow were measured in a spheric particle-bed with air, water and small particles of solid glass or aluminium oxide.The influences of flow rate, particle size and properties on the pressure drop and holdup were examined, and the characteristics of large and small particles were also compared. Some empirical correlations presented by other authors were modified, and the final results quite satisfactory.更多还原
