The effects of powder plug characteristics in a horizontal pipe were investigated both numerically and experimentally. The results show that the pressure drop depends on the dynamic friction coefficient of powder as well as the plug characteristics. The correlation between the dynamic friction coefficient of powder and the plug characteristics revealed that the pressure drop should be estimated from the dynamic wall friction coefficient at a low plug velocity, whereas it should be estimated from the dynamic internal friction coefficient at a high plug velocity.
