Department Department of Applied Mathematics


Dr JiYoun Arns is currently working as a 3D CT image data analyst who works in the multidisciplinary projects with Civil eng, Manufacturing and mechanical eng, Petroleum eng, BEES and SPREE to integrate the different imaging techniques or other lab measurements by supporting the findings of different research projects with the 3D direct image based numerical calculation. She worked as X-ray instrument scientist (https://www.engineering.unsw.edu.au/petroleum-engineering/alumni-industr...), previously developed the successful acquisition of  mice leg image with muscles, 4D cement hydration imaging and in-situ multiphase flow imaging. Her research was  multi phase flow through porous media to understand the flow mechanism. The knowledge of pore-scale multi phase flow ultimately enhances efficient oil and gas recovery as well as prevents the contamination in underground water resource. Pore-scale network modeling is another way to upscale the micro scale details to calculate macro scale flow or structural properties. Her PhD is about pore scale network modeling for three phase flow to abstract/understand the effect of pore geometry and topology in multi phase flow. Imaging processing & acquisition for Digital Core Technology are her main expert and she has previously worked a number of PhDs and MDs in UNSW, ANU and Helmholtz center for environment research. (https://physics.anu.edu.au/appmaths/people/profile.php?ID=629&tab=publications)
