Abstract The protection of underground civil infrastructure continues to be a high priority for transportation and transit security agencies.In particular, rail transit tunnels running under bodies of water are susceptible to disruptions due to flooding caused by extraordinary climatic events such as hurricanes or other events resulting from human

The radiator of special vehicle often exposed to sand condition, and the sand have great influence on the performance of radiator, in order to figure out the impact, the physical model of a radiator is built, the three-dimensional numerical simulation of the gas and water flow field of the radiator is carried out by adopting Collections discrete ph
