EFFECT OF SCALE FACTOR ON INFRARED RADIATIOIN CHARACTERISTICS OF MARINE EXHAUST SYSTEM WITH INFRARED SIGNATURE SUPPRESSION DEVICE AND ITS CORRECTION
模化比对船用排气红外抑制装置红外辐射特性的影响及修正

Based on the results of calculation and measurement of the two kinds of marine gas turbine exhaust systems with the infrared signature suppression devices, according to the similarity theory, the effects of scale factor on the temperature profile (of air flow and tube wall), and infrared radiant intensity(of exhaust plumes and exhaust uptake inner wall) of the exhaust system were analyzed and discussed. Based on the corresponding parameters of real ship exhaust systems as well as the magnitude of scale factor impacts, the recommended values for selecting the scale factor were estimated and presented.
