He developed a large experience in raw materials, melting and floating process and defect analysis. He is now working as a CFD Engineer and trainer at CelSian.
Cristian Hernández
Cristian Hernández graduated as a Materials Engineer from the University of Antioquia, Colombia. Then he obtained a Master’s degree in Metallurgical and Materials Science at the University of Sao Paulo, Brazil. He worked for 8 years as a Glass Science engineer at OI for different plants in South America, supporting them in color changes, glass quality issues, furnace and batch house ramp-ups, raw materials standardization and implementation of new ones. He joined Celsian as a Project leader acting as a supporter and technical advisor.
Aled Meulenbroek
Aled Meulenbroek obtained a Master’s degree in Applied Physics at Eindhoven university of technology, specializing in fluid mechanics. He also holds a PhD degree in mechanical engineering on “Marangoni effects on hydrogen bubbles on a microelectrode”. He is passionate about Marangoni effects, fluid dynamics, heat transfer and the behaviour of bubbles in glass. He is experienced in supervising/educating students in fluid dynamics. Aled joined CelSian as a CFD engineer where he models glass furnaces and as a trainer at the CelSian Academy.
Arca Iyiel
