Study on enhanced heat transfer characteristics of point sound source
For the actual engineering problems,the point sound source model was adopted,and Fluent software was used to carry out simulation research on the enhanced heat transfer per-formance of the point sound source,and the position,amplitude and frequency of the point sound source were accurately controlled through the udf program,so as to simulate the influence of the flow on heat transfer performance by the acoustic wave in the actual engineering problems.The re-sults show that the heat transfer coefficient is increased by 477.3％when the sound source is lo-cated in the middle of the pipe in the flow channel where the diameter of the front and rear pipes changes abruptly,compared with that when there is no sound wave.Meanwhile,the enhanced heat transfer effect increases and then decreases with the increase of sound wave frequency,and increa-ses with the increase of amplitude.
