Results of the Experimental Study of the Effect on Compressor Parameters from Water Admitted at the Inlet to a Centrifugal Compressor
Abstract
The following were among the conclusions of this study: (1) Injection of water on suction into a compressor for evaporative cooling of air considerably decreases the air temperature on exit from the compressor; (2) During compressor tests, total evaporation of the injected moisture occurred to the state of saturation with different turns and different positions of the butterfly valve; (3) Evaporative cooling of air during compression in a centrifugal compressor operating at n = const decreases the power required by the compressor; (4) Evaporative cooling increases the degree of pressure rise and the air flow rate; and (5) Introducing evaporative cooling causes the characteristics curves of the compressor to shift somewhat into the region of high flow rate in connection with the increase in air density on the exit from the impeller.
