摘要
建立了液滴喷射过程流场和温度场的计算模型,研究了在外加周期性正弦扰动作用下,石蜡液滴形成过程的流场和温度场及其变化情况,给出了不同扰动频率下所形成液滴的形态及其变化规律,得出了比较均匀的液滴流,指出扰动频率对液滴的形成及其均匀性具有重要影响。模拟结果与文献中的实验结果吻合较好。
The changes of flow field and temperature field for wax droplet formation process by external periodic sinusoidal disturbance are studied based on computational fluid dynamics software FLUENT. The morphology of droplets at different disturbance frequencies is simulated, and the uniform droplet stream is obtained. By simulation, it is known that the disturbance frequency has a good effect on the droplet formation and its uniformity. The numerical results agree well with the experimental ones in the literature .
