Analysis of Effect and Mechanism of Different Type Buffer for Reducing Pressure Pulsation

Abstract

Abstract. The pressure pulsation of network can be reduced effectively by using buffer, discussing the effect of the tangential inlet buffer and radial buffer with different outlet conditions. The reason that affects buffer performance can be gotten through the analysis of internal flow flied and fluid path lines of different buffers. Five groups experiments of different outlet pressure of the compressor are used to provide boundary conditions for Fluent simulation calculation .The result shows that the tangential inlet buffer has better performance than radial inlet buffer for different pressure level.
