タイトル(掲載誌)航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-9
一般注記A finite volume method for the solution of three-dimensional incompressible steady Navier-Stokes equations based on a general curvilinear coordinate system was employed to study the characteristics of turbulent flow in dump diffuser of gas-turbine combustor. The standard k-epsilon turbulence model is used to characterize the effect of turbulence. In order to achieve a saving in CPU time for calculation, present calculation was performed by lending itself to vector computer architecture of the Supercomputer FACOM VP-50. This method is applied to prediction of turbulent flow in a three-dimensional dump diffuser with and without the fuel nozzle. The calculated results are compared with the corresponding experimental data obtained in this work. General features of the flow pattern are adequately predicted although discrepancies in detail seem to indicate deficiencies in the turbulence model used in present study.
