Abstract: At present there are 3 main kinds of means for atmospheric environmental researches, i.e., experimental simulations, numerical simulations and field experiments. For experimental simulations, in addition to the wind tunnel experiment, the towing tank modeling study is keeping on development in recent years. To improve its experimental ability in this aspect, CIRP had erected a large environmental simulation towing tank and related test equipments. The structure of the tank simulation system, as well as its performance and features, are presented in this paper. A series of preliminary experiments have confirmed its effectiveness in the simulation of pollutant relocationdiffusion in atmospheric environment.
