Add   Multiphysics modelling of ultrasonic melt treatment in the hot-top and launder during direct-chill casting: Path to indirect microstructure simulation
Authors: Beckwith, Christopher | Djambazov, Georgi | Pericleous, Koulis A. | Subroto, Tungky | Eskin, Dmitry G. | Roberts, Dan | Skalicky, Ivan | Tzanakis, Iakovos
Source: Metals. 2021. Vol. 11, № 5. P. 674 (1-14)
Type: статьи в журналах
Date: 2021
Description: This study concerns the numerical simulation of two competing ultrasonic treatment (UST) strategies for microstructure refinement in the direct-chill (DC) casting of aluminium alloys. In the first, mo ... More
Add   New insights into the mechanisms of ultrasonic emulsification in the oil–water system and the role of gas bubbles
Authors: Wu, W. H. | Eskin, Dmitry G. | Priyadarshi, Abhinav | Subroto, Tungky | Tzanakis, Iakovos | Zhai, W.
Source: Ultrasonics sonochemistry. 2021. Vol. 73. P. 105501 (1-10)
Type: статьи в журналах
Date: 2021
Description: Ultrasonic emulsification (USE) assisted by cavitation is an effective method to produce emulsion droplets. However, the role of gas bubbles in the USE process still remains unclear. Hence, in the pre ... More
Add   Numerical modelling and experimental validation of the effect of ultrasonic melt treatment in a direct-chill cast AA6008 alloy billet
Authors: Subroto, Tungky | Lebon, Gerard Serge Bruno | Eskin, Dmitry G. | Skalicky, Ivan | Roberts, Dan | Tzanakis, Iakovos | Pericleous, Koulis A.
Source: Journal of materials research and technology. 2021. Vol. 12. P. 1582-1596
Type: статьи в журналах
Date: 2021
Description: In this work, we study how ultrasonic cavitation melt treatment (UST) affects the temperature distribution, sump profile, and resulting microstructure in the direct-chill (DC) casting of an AA6008 alu ... More
Add   On the governing fragmentation mechanism of primary intermetallics by induced cavitation
Authors: Priyadarshi, Abhinav | Khavari, Mohammad | Subroto, Tungky | Conte, Marcello | Prentice, Paul | Pericleous, Koulis A. | Eskin, Dmitry G. | Durodola, John | Tzanakis, Iakovos
Source: Ultrasonics sonochemistry. 2021. Vol. 70. P. 105260 (1-16)
Type: статьи в журналах
Date: 2021
Description: One of the main applications of ultrasonic melt treatment is the grain refinement of aluminium alloys. Among several suggested mechanisms, the fragmentation of primary intermetallics by acoustic cavit ... More
Add   Scale up design study on process vessel dimensions for ultrasonic processing of water and liquid aluminium
Authors: Khavari, Mohammad | Priyadarshi, Abhinav | Subroto, Tungky | Beckwith, Christopher | Pericleous, Koulis A. | Eskin, Dmitry G. | Tzanakis, Iakovos
Source: Ultrasonics sonochemistry. 2021. Vol. 76. P. 105647 (1-13)
Type: статьи в журналах
Date: 2021
Description: Scaling up ultrasonic cavitation melt treatment (UST) requires effective flow management with minimised energy requirements. To this end, container dimensions leading to the resonance play a crucial r ... More
