Numerical investigation of gas-liquid two-phase cold-flow around bluff-body stabilized burners

  • 摘要: 提出并建立了基于可变时间间隔平均方法的多尺度两相湍流模型,通过算例验证,证实了所推导的气液两相多尺度数学模型、所标定的模化参数及描述气液两相作用机理的合理性,及其计算的时间平均阻力系数、脉动升力系数误差、斯特劳哈尔数和回流区大小误差分别为1.45%,0.323%,2.17%,2.33%,计算结果明显优于标准k-ε 和重整化群(RNG)k-ε模型.用多尺度湍流模型对气液两相绕流6个不同的钝体稳燃器进行数值计算表明:船形与锥形是综合性能较优的两个钝体稳燃器结构.其中,船形钝体比锥形钝体稳燃器回流区大10.53%,其时间平均阻力系数比锥形稳燃器大4.776%,方均根脉动升力系数比锥形稳燃器小44.73%,通过全方面综合比较,船形是综合性能最优的钝体稳燃器结构.
