摘　　要：首先从密合性和舒适性的角度阐述了口罩目前存在的问题,介绍了口罩在原材料和结构改良方面的研究进展。然后,从人体头部和口罩模型的建立、气体流场的数值模拟及死腔的改进等三个方面,综述了计算流体力学在口罩与面部之间空隙内气体流场及口罩舒适性方面的研究现状,指出利用气体流场数值模拟可得到口罩与面部之间空隙内的气体速度、温度和组分浓度的分布,能为口罩的设计提供依据。最后,对未来的发展方向进行了探讨。Firstly, the existing problems of mask were described from the perspective of tightness and comfort, and the research progresses of improving mask from the aspects of raw materials and structure were introduced. Then, from three aspects, including the establishment of human head and mask model, numerical simulation of gas flow field and improvement of dead space, the research status of computational fluid dynamics in gas flow field in the gap between mask and face, and mask comfort were reviewed. And it was pointed out that the distribution of gas velocity, temperature and component concentration in the gap between mask and face could be obtained by the numerical simulation of gas flow field, which could provide the basis for mask design. Finally, the future development directions were discussed.
