Title of the thesis:Experimental ice shape mapping by means of 4D-scanning
Summary:When studying ice accretion processes experimentally, it is desirable to document the generated ice shapes as accurately as possible. The obtained set of data can then be used for aerodynamic studies, the improvement of icing test facilities, the development of design criteria, the validation of ice accretion simulation tools as well as other applications. In the past, various ice shape documentation methods have been established including photography, cross-sectional tracing, molding and casting as well as 3D-scanning. This work introduces a new ice shape documentation technique, based on active 3D-scanning in combination with fluorescent dyes and an optimized set of optical filters. This new approach allows recording the time-resolved, three dimensional growth of an arbitrary ice shape. Based on this concept, a so-called 4D-scanning process is developed, which allows a detailed evaluation of icing experiments and hence a better understanding of the ice accretion process itself. The scanning system has been successfully implemented and tested in FH JOANNEUM's small-scale icing wind tunnel. An appropriate evaluation tool was developed, which allows the semi-automatic evaluation of the generated data in view of accreted ice volume, ice thickness and ice roughness. As an outlook to future work, the experimental results are compared to numerical simulation results generated with FH JOANNEUM's icing code ICEAC2D.
Key words:3D-scanning, 4D-scanning, time resolved, ice shape mapping
