Abstract A thorough understanding of droplet impact and freezing is vital in preventing ice accretion on many outdoor devices.This simulation-based study investigated the effect of surface morphology on the impacting-freezing process of a supercooled droplet.Also, the variations of Weber number and supercooling temperature Dresses were studied nume
Concrete mortar segregation during vertical pipeline gravity transportation will form a weak part in the shaft lining, which poses a challenge for deep mine shaft safety.The specific gravity difference between aggregate and slurry will cause relative motion; the relative velocity is detrimental to the mortar workability, which plays a significant r
In multi-agent reinforcement learning, the cooperative learning behavior of agents is very important.In the field of heterogeneous multi-agent reinforcement learning, cooperative behavior among different types of agents in a group is pursued.Learning a joint-action set during centralized training is an attractive way to obtain such cooperative beha
