METHOD OF VENTILATING DESIGN FOR HIGH SPEED TRAIN

For the characteristic of high closing in compartments of high speed train, the ventilating design should ensure passengers' safety and comfort. Since the traditional method of temperature and velocity distribution depending on free jet experimental equations ignores the effects of push pull flow and obstacles, the ventilating design mainly depends on modeling experiments. By regarding the push -pull flow and the shape of compartment and the seats as an integer, the method in this paper directly simulates temperature and velocity distribution to ensured the demands of comfortable air conditioning ,in the meantime ,it can conveniently obtain feeding velocity and feeding temperature difference .This method is not only applied to ventilating design of high speed train but also applied in ventilating design of general manned train and of aircraft's cabin.
