| 摘 要： | 内燃机缸内湍流的研究是个十分重要而且复杂的课题,数值模拟技术为其提供了有效的研究方法.本文利用CFD软件KIVA分别采用标准k-ε,RNGk-ε模型在无旋流和有旋流的两种工况下,对轴对称的ω型燃烧室内的湍流流动进行二维和三维数值模拟计算,并把计算结果与实验数据进行对比,得到了内燃机缸内湍流流动的特性.本文为内燃机港内湍流研究提供了一种比较好的研究方法,此方法和计算结果为内燃机的性能开发与优化设计提供依据. |

| Abstract: | Turbulent flows in the cylinder of internal combustion engines are invariably complicated. Numerical sim- ulation is a good way to solve the problem. This thesis performs comparative study on three versions of eddy - viscos- ity models （EVM）, i. e. conventional k - e model, RNG k - e model. 2 - D and 3 - D numerical computations are carried out for o0 combustion chamber. The effects of swirling and curvature are taken into account. The text com- pares the result with the experimental data and obtains the character of turbulent flows of internal combustion en- gines. This thesis provides a well method to study turbulent. The result and method provides the laws of diesel en- gine development and optimum design. |
