Abstract: The purpose of t h i s paper is to discuss the phenomena of surge as applied to c e n t r i f u g a l or a x i a l compressors, and to look at some b a s ic approaches to surge c o n t r o l. GENERAL In the e a r l y y e a r s , gas compression was done mostly with r e c i p r o c a t i n g or c y l i n d e r type machines, because the q u a n t i t i e s being handled were not l a r ge by t o d a y s s t a n d a r d s , and because there was not the emphasis on development of o t h e r types of machines. However, with the i n c r e a s i n g use of gas, along with demands for c r o s s - c o u n t r y t r a n s m i s s i o n in e v e r - i n c r e a s i n g q u a n t i t i e s , the a x i a l and c e n t r i f u g al compressors gained in importance. Today, n e a r ly a l l compression is handled by such machines. The problem of surge, which did not e x i s t with the e a r l i e r machines, proved to be a s e r i o u s one, since i t could destroy a compressor
