对进气歧管和排气歧管流量分配系统的性能进行了分析研究。主要重点放在侧管在与歧管轴线成直角的情况下形成尖边连接的结构。根据流道上的动量平衡，建立了描述离散分支点流动行为的数学模型。将该模型推广到均匀多孔歧管连续排放或连续进气的情况。得到了控制流量分配方程的数值解，并与实验数据进行了比较。从分析模型出发，建立了表征歧管性能的无量纲参数。
An analytical investigation of the performance of flow distribution systems was conducted for both intake and exhaust manifolds. Primary emphasis was placed on configurations in which the lateral tubes formed sharp-edged junctions at right angles to the manifold axis. A mathematical model describing the flow behavior at a discreet branch point was formulated in terms of a momentum balance along the manifold. The model was extended to the case of continuous discharge or intake for a uniformly porous manifold. Numerical solutions of the governing flow distribution equation were obtained and compared with experimental data. Dimensionless parameters characterizing the performance of manifolds were formulated from the analytical model.
