The research is concerned with the application of heat transfer and fluid flow to certain aspects of optical fiber production. Such fibers are used in telecommunications, sensors, and medical applications. The focus of the research is the deposition of an ultra-fine aerosol on the inside surface of a high-purity silica tube which serves as the substrate of the optical fiber. Heat transfer is the dominant mechanism in the aerosol formation and in its transport to the tube wall, and radiation heat transfer is especially important at the high temperature level of the process.

该研究涉及传热和流体流动在光纤生产的某些方面的应用。 此类光纤用于电信、传感器和医疗应用。 研究的重点是在作为光纤基材的高纯度石英管的内表面沉积超细气溶胶。 传热是气溶胶形成及其向管壁传输的主要机制，辐射传热在过程的高温水平下尤其重要。
