摘要

考虑了亚微米气溶胶粒子在模型过滤器中的沉积，该模型过滤器由微米尺寸的纤维组成，其表面含有径向纳米须（针）。在考虑气体滑移效应的情况下，对模型过滤器中横向三维斯托克斯流场进行了数值模拟。计算了纤维阻力和纤维收集效率是晶须长度、堆积密度和纤维间距的函数。确定了光纤收集效率与粒子半径的关系。

Deposition of Submicron Aerosols in Filters Composed of Nanowhisker-Coated Fibers

The deposition of submicron aerosol particles in model filters consisting of micron-sized fibers containing radial nanowhiskers (needles) on their surfaces is considered. Numerical simulation has been performed for the transverse 3D Stokes flow field in a model filter—an isolated row of whisker-coated parallel fibers taking into account the gas slip effect on their surface. The fiber drag force and the fiber collection efficiency have been calculated as functions of the length and packing density of the whiskers and the distance between the fibers. The dependence of the fiber collection efficiency on the particle radius has been determined.

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
