本文介绍了一套面向研究的计算流体动力学（CFD）3D模型，用于模拟研磨过程中的流体流动和传热。这些模型的最重要的功能进行了描述，并提出了一些代表性的模拟结果，沿着与出版的实验数据进行比较。详细地得到了研磨区内和研磨区周围的温度、压力、速度和液体体积分数的分布。这些结果对于研究研磨液对研磨过程的影响以及确定给定应用的最佳流体成分和供应参数至关重要。模拟结果与实验的全局流量、温度和压力值吻合良好，表明CFD模拟在磨削应用中的可行性。
This paper introduces a set of research oriented computational fluid dynamics (CFD) 3D models used to simulate the fluid flow and heat transfer in a grinding process. The most important features of these models are described and some representative simulation results are presented, along with comparisons to published experimental data. Distributions of temperatures, pressures, velocities, and liquid volume fractions in and around the grinding region are obtained in great detail. Such results are essential in studying the influence of the fluid on the grinding process, as well as in determining the best fluid composition and supply parameters for a given application. The simulation results agree well with experimental global flow rates, temperature, and pressure values, showing the feasibility of CFD simulations in grinding applications.
