Title: Suppressing Infrared Radiation through Fibrous Thermal Insulation Materials

Date/Time: December 06, 2023, 13:40 - 14:30

Location: FENS G032

Abstract:  My talk will focus on our research on the interaction of infrared radiation with aerospace materials. In particular, I will present various studies conducted by my group related to the suppression of infrared radiation through fibrous thermal insulation materials in collaboration with NASA with the support of AFOSR. In this talk, I will present our studies related to the computational models of radiative heat transfer through fibrous thermal insulation protection materials. For thermal insulation problems in aerospace materials, radiation becomes an important part of the thermal budget. Especially at high temperatures, radiative heat transfer through insulation materials exceeds the conductive heat transfer. Fibrous media are potential candidates for operation in extreme environments due to their broad temperature operation range, their excellent thermal stability at high temperatures, thermomechanical advantages due to high porosity and good thermal properties. In addition to these properties, they exhibit attractive optical properties due to dominant scattering and absorption by cylindrical fibers in certain spectral regions. For effective use in extreme environments as thermal insulation, engineering the scattering and extinction spectra of unbonded high-temperature insulation, such as unbonded shuttle silica fibers (Q-fiber), is of great interest. I will present our initial investigations on computational models for the interaction of incident radiation with fibrous media

Bio: Kursat Sendur received his Ph.D. degree in 2001 from The Ohio State University, where he worked as a graduate research associate and then as a postdoctoral researcher. In 2002, he joined Seagate Technology Research Center, USA where he worked on plasmonic transducers, near-field thermal radiation, and recording medium in heat assisted magnetic recording, an emerging data storage technology. Between 2005-2007 he worked at Advanced Microsensors, Boston, USA on thin-film sensor technologies. Since 2007, he has been a faculty member at Sabancı University in Istanbul, Turkey.
