Experimental Platform Design on Flowing Resistance of Air Vents for Bullet Train
摘要
Abstract
Problems about an experimental platform are discussed,recurring to which,the flowing resistance of air vents on the bullet train can be researched.According to the principle of fluid mechanics,it is put forward that the train wind field outside can be simulated by the low speed wind tunnel,the ventilation test piece is placed in the test section of wind tunnel,the wind speed outside and the flowing rate through the air vents are tunable,then a experimental platform for flowing resistance of air vents is built.The experimental results show that the scheme of the experimental platform is feasible,and the measurement results are credible.关键词
