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 discrete phase model (DPM) as well as the SIMPLE scheme. Then, the relationship between different factors (such as air velocity, sand particle size, sand concentration) and heat transfer coefficient are obtained by means of simulation, which provides a basis for the optimization design of the special vehicle radiator. A test bench is built, and the simulation is verified to be correct by comparing the simulation result with the test result.
Key words: Sand / Special vehicle / Heat dissipation performance / Gas-solid two-phase flow
