| Summary: | This paper presents a numerical analysis of the transmission loss (TL) for perforated steam generator system by adapting the theory of transmission of acoustic wave in an automotive exhaust pipe. The objective of this study is to develop a computer program to predict the transmission loss of a perforated steam generator and to investigate the influence of porosity and the effect of outlet-inlet parameters on the performance of steam generator. The efficiency and capabilities of the computing the transmission loss is compared to the experiment results obtained from the previous established research paper that the results give a good agreement. In this study two sets of results are presented. The first set illustrates the determination of the sound pressure level at one point and, then at another point after the sound wave traverses a certain distance. The second set of results describes the transmission loss of the acoustic wave after passing through steam generator. |
