Question

Complete breakdown of steady flow through compressor due to periodic flow reversal, is known as

• A. choking
• B. surging
• C. stalling
• D. purging

Answer 1

The correct option is B surging

Surging is the complete breakdown of steady flow through compressor due to the periodic flow reversal. Stalling is the aerodynamic flow separation from the blade profile due to the improper design of blade. Maximum mass flow-rate in the compressor is known as choke limit. Purging is the removal of non-condensable gases from the condenser.
