为了更好的分析夜里偶合器内流场的流动情况,本文利用计算流体力学(CFD)方法对偶合器内部三维流场进行了数值模拟计算,根据计算结果对内流场的速度与压力分布进行详细的分析。对液力偶合器的制动工况、牵引工况( =0.5)和牵引工况( =0.8)的实验结果与数值计算结果进行对比分析。全文的主要研究内容有以下几个方面:

(1) 流体流动要受物理守恒定律的支配。而控制方程使这些守恒定律的数学描述,本文给出了几个流体动力学控制方程,并根据情况指出了本文采用的流体动力学控制方程。

(2) 根据确定的分离流动控制方案建立液力偶合器的三维几何模型,并对其进行网格离散,设置适当的边界条件。在此基础上选出适合本算例的湍流模型、速度-压力耦合算法以及离散格式,利用流体分析软件对泵轮输入转速为800rpm时,不同工况下的内部流场进行数值模拟。

(3) 根据数值模拟结果,分别对制动工况( =0)、牵引工况( =0.5)以及牵引工况( =0.8),泵轮分别输入转速为800rpm时,液力偶合器内部流场的速度分布和静压力分布进行分析。

(4) 经过上述研究 总结处相关结论。

In order to better analysis of the night coupling flow within the flow, the paper use computational fluid dynamics (CFD) methods of coupling within the three-dimensional flow field of numerical simulation, according to the results of the internal flow speed and pressure distribution Detailed analysis. On the brake fluid coupling conditions, traction conditions (= 0.5) and traction conditions (= 0.8) and the experimental results of numerical results were analyzed. The full text of the main contents include the following:

(1) fluid flow is subject to the law of conservation of the physical domination. The equation of the law of conservation of these mathematical description of this paper, several fluid dynamics equations, and under circumstances that the paper used in fluid dynamics equations.

(2) According to determine the flow control from the establishment of the programme hydraulic coupling of the three-dimensional geometry model, and its grid discrete provis
