inlet boundary meaning in Chinese
入口边界
Examples
- The hub leakage flows were modeled and calculated in two different ways : the flow fields inside hub axial gap were calculated together with blade passage flow in an integrated manner , and the leakage flows due to the hub axial gap were modeled as inlet boundary conditions
计算时分别采用了两种模化途径，即耦合求解转子上游叶根间隙内空腔与转子通道内的流场，以及求解将叶根同间隙模化为进口边界的转子流场。 - Turbulence over flat wall is presented with the cfd software cfd ace ( u ) when given by various inlet boundary conditions , subgrid model and turbulence intensity under the two - dimensional circumstance . on comparing these outcomes with the experimental data , we can analyze the impacts that all these factors have on the development of flow boundary layer
采用计算流体力学软件cfdace ( u ) ，在二维情况下应用不同的进口边界条件、亚格子模型和来流湍流度对平壁流动进行大涡模拟，并将模拟结果与已有的实验结果进行对比，分析比较了这些因素对流动边界层发展的影响。 - Certain discrepancy remain between the simulation results and the experiment results , not only caused by the turbulent model , but also by the simplification of the inlet boundary condition and the mesh generation . modeling gas - particles interaction flows is complex . in this thesis , gas - phase transport equations coupled with the gas - particle interaction are derived based on the dsm turbulent models to handle the interaction of momentum and kinetic energy of turbulence between the gas and particles
分离器内的固体颗粒运动采用涉及湍流扩散影响的随机轨道模型和确定轨道模型，同时在湍流模型中加入了颗粒影响的源项，在流场计算的基础上，模拟了不同直径的颗粒在分离器内的运动规律及颗粒分离效率，并同理论和实验得到的数据进行了比较。 - Results from this investigation show that the loss generation within the coolant holes is substantial and that ejection into regions of low static pressure increases the loss per unit coolant mass flow . the results also reveal strong interactions between endwall coolant ejection and secondary flow in the blade passage . the secondary flow has a strong influence on coolant trajectories and coolant ejection delays the three - dimensional separation of the inlet boundary layer on the endwall , chang the secondary flow and reduces its associated losses
本文的研究成果显示，冷却孔内产生的损失是主要的，并且低静压区域的冷空气喷射会增加单位冷空气质量流的消耗；喷射的冷空气与叶栅端壁流场之间有强烈的相互作用；二次流对冷却空气的流动轨迹有较强的影响；冷空气喷射能延缓端壁入口边界层的三维分离、改变二次流从而减少其相关损耗。
