中文摘要：
在磨削加工中,由于砂轮高速旋转在砂轮表面形成空气附面层,特别是在工件与砂轮楔形间隙内,附面层的压力场与速度场急剧变化,且在楔形间隙内出现了明显的返回流,严重制约磨削液的有效注入。利用附面层和流体力学理论建立了平面磨削中楔形区气流场的数学模型,并进行了仿真研究,结果表明：随着砂轮线速度的增大,楔形区的气流压强增加,气流速度也随之增大;随着砂轮与工件间最小间隙的减小,楔形区气流压力、水平方向气流速度以及垂直方向气流速度明显增加,返回流趋于剧烈,流场能量增加。
英文摘要：
In the plane grinding process, an air boundary layer named gas barrier is generated around the wheel, the pressure and velocity of air flow change rapidly especially in the wedge-shaped gap between workpiece and wheel. And caused by the high-speed rotation, back flow is generated in the wedge-shaped gap, which is seriously harmful to the injection of grinding fluid. Applying fluid mechanics and boundary layer theory, the theoretical model of air flow in the plane grinding is established and simulated. The results as follow： with the higher wheel speed, the pressure and velocity of wedge-shaped gap is larger, and the back flow is more intense. The pressure and velocity of wedge-shaped grow larger and the back flow grows more intense with a smaller wedge-shaped gap.
