When the conceptual design phase or the modification design phase, it is essential to confirm realistic predictions of the 1-D air distribution ratio inside the combustor which has the complicated geometry. This accurate initial design would make that the less time is spent on following design period like 3-D CFD analysis and test. There are many research which have performed on the internal flow but these researches have focused on the simple shape like a circular pipe, an annular pipe, an orifice and so on. However, the configuration of the gas turbine combustor does not consist of simple configurations. Therefore, many researches have focused on the way to simplify the combustor geometry and on the correlation for the real combustor configurations. The purpose of this study is to verify the 1-D flow network modeling using the effective area test and define the air distribution ration of the combustor. The commercial 1-D network tool, ‘Flowmaster’ is used for 1D flow network modeling.
