Compressor Critical Response Time Determination Study
Abstract
Critical response time may be defined as the time period or duration of a compressor inlet flow distortion required for a significant effect on compressor stability. The knowledge of this time period is important as a basis for evaluating time variant inlet distortion data for its potential impact on compressor stall margin. This period can be related to the time required for fluid to travel the length of a compressor by defining a reduced frequency parameter. Critical response time can be defined for any compressor, once the critical value of reduced frequency is ascertained. Results of a mathematical model of a compressor system demonstrate that the critical value of reduced frequency is between 1.0 and 5.0. An inspection of available data indicates that a value of approximately 2.0 is the critical value.
