Investigation of the Atomization Cooling in Transportation Channel Based on Dispersed Phase Model

A turbulent heat transferring model of the airflow in transportation was modeled, and the simulation result by it was compared with the measured data. The turbulent diffusion of droplets was simulated by stochastic model in Lagrangian coordinates, and PSIC method was used for simulating two direction coupling between air and droplets. The influence to the effect of atomization cooling by the diameter of the droplets, the initial velocity and the velocity of the airflow at inlet were analysed. With the increment of the velocity of the airflow at inlet, the temperature of the airflow changed as power functions. And critical values of the diameter of the droplets and the initial velocity are existed. If the value greater or less than the critical value, the effect of the cooling project would be weakened.
