Heating is an undsirable effect of the compression process at least as far as compressors are ocncerned and heat transfer is nature's way of driving systems towards stability.This has not only provided food for thought for researchers trying to understand its influence and quantify its effects,but also challenged designers to mitigate its impact and develop safe and efficient desings.Also,just as any other unwanted phenomenon would spur curiosity and inventivenness,this has led to hte development of a host of ne wmaterials both metallic as well as non-metallic to withstand the vagaries of thigh temperatures,in addition to the toxic environment present in many gas ocmpressors used in pumping and process industries.This paper is an attempt to present some o the problems created by this unwanted phenomenon,review the ocntributions of some of the past investigators,and kindle more interest for furthering the advancement of compressor technology.
