Abstract(J) | 本研究の目的は,ガスパーセル法を用いた噴流解析の高精度化である.乱流モデルには圧縮性を考慮したLESを用いている.天然ガス噴流挙動は,噴射ガス全体を数万個の代表粒子で表現するガスパーセル法の導入や燃料の多成分化を行うことで再現している.定容容器における自由噴流解析で得られた結果をシュリーレン実験結果と比較することにより,解析結果の精度検証を行った. Translation |
Abstract(E) | The purpose of this study is to improve the accuracy of the numerical simulation of jet flow using the gas parcel method. The turbulence model is the LES. A convection term scheme suitable for the numerical simulation of jet flow using the gas parcel method is investigated. The calculation accuracy was verified by comparing the experimental results with the methane jet calculations. The calculation of natural gas jet is possible by considering multicomponent fuel. The effects of the diffusion coefficient on penetration and radial spread of the jet were investigated by comparing methane and natural gas jets. |
