| 摘 要： | 针对发展高效低污染旋流燃烧技术的需要,对旋流燃烧室内两股同轴旋转射流相互作用的湍流旋流流动进行了数值模拟.计算中采用了一种新的代数Reynolds应力模型和QUICK离散格式.在两股射流同向旋转和反向旋转两种条件下,将模拟得到的燃烧室内湍流旋流流动的时均气体轴向速度场、切向速度场和静压场与实验数据进行了比较.

| Abstract: | For the purpose of developing swirl combustors with high combustion efficiency and low pollutant emission, a numerical simulation of swirling turbulent flows in a swirl combustor with coaxial jet interactions is performed. A new algebraic Reynolds stress model and the QUICK discretization scheme are utilized in the present calculations. The simulated results of swirling turbulent flows in the combustor for both cases of the coswirl jets and the counterswirl jets are in agreement with the experiment data in terms of the time-averaged gas axial velocity, tangential velocity and static pressure. |
