The numerical simulation of the flow field on toilet of environmental protection and energy saving for the long-distance train

The commercial computer fluid dynamics software package FLUENT was used to simulate the flow field of the new toilet system. The mesh model of the flow field was built with the GAMBIT. With the numerical simulation of the flow field on air intakes and flushing system, the pressure and velocity vector cloud diagram have been given. The information would be very useful in experimental investigation. The study has offered the significant theoretic reference to optimize the toilet system.
