摘  要:
应用Fluent软件对某机型柴油机进气歧管进行三维流场的模拟计算,并且对歧管内部进行流动特性分析,对比分析两种进气歧管结构的出口截面速度、歧管内的气流流速及湍流动能。结果表明,缩小歧管之间的距离有利于改善柴油机各缸的进气均匀性,增加进气量,进而提高发动机的性能。

摘  要:
The three-dimensional flow field of a type of diesel engine intake manifold was simulated by FLUENT,and the flow characteristic of its interior was analyzed.The exit velocity,manifold air flow velocity and turbulence kinetic energy of two kinds of intake manifold structure were comparatively analyzed,which shows that narrow the distance between the manifold is good to improve the intake evenness of each cylinder,thus increases the volume and improves the performance of the engine.
