The sinking dynamics of a solid intruder in concentrated cornstarch suspensions studied using ultra-fast Magnetic Resonance Imaging

Key Points

• This research aims to understand how solid intruders behave when submerging in concentrated cornstarch suspensions.
• Utilized ultra-fast magnetic resonance imaging to observe sinking dynamics.
• Analyzed the behavior of intruders in opaque cornstarch suspensions.
• Focused on localized and transient dynamics that are hard to measure otherwise.
• Identified key patterns in the sinking process that vary with different intruder shapes.
• Found that the suspension's properties significantly influence sinking speed and stability.
• Revealed that localized dynamics are critical to understanding the overall behavior of intruders.
