Railway Passenger Air Distribution Simulation And Evaluation

The object of this paper is the railwar air conditioning car.Detects the possibility ofcalculating the three-dimension temperature field and velocity field in the car with heat source bynumerical simulation. by simulation flow in the car, learns about the change of the field indifferent supply form and parameter, and provides a reference to the designing of the railway carair conditioning.Itis the first time to use numerical simulation in the research on the air distribution of railwayair conditioning car. Based on the theory analysis, combines numerical with prototypeexperiment and mainly usese the former. Makes the simulation on the flow field in the car by the qare PHOENICS, comp the result with the experiment and the result is reasonable. Souses numerical simulation in the evaluation of car air distribution in the evaluation of car air distslotted inlet andgrid inlet on ceil is the well supply form. Due to the well comfortable condition ,being able tocombine with the air conditioning units at the bottom of the car and its high IAQ, chair back inletraised the first time by this paper can be popularized. Inlet under the table can not be used becauseof its bad comfortable condition. Investigates and analyses the comfortable condition of the airconditioning car presently, provides reasonable proposition and it is beneficial to the increase ofcomfortable degree, energy saving and control.It is feasible that use numerical simulation to analysis and evaluate the air distribution in a car.Provides a solid foundation to forecast, analyze and evaluate the reasonable aie distribution in the air conditioning car.
