Abstract :
The present work studies the pulsation attenuation characteristics of expansion chamber. First, the work principle of expansion chamber is studied. Then, the flow fields of expansion chambers with different sizes are simulated with CFD simulation software. In addition, analyze in detail the relationship between the pulsation attenuation characteristics of expansion chamber and expansion chamber parameters.
