Coalescence of Printed Yield Stress Filaments in Direct Ink Writing
Hugo L. França, Daniël Tieman, James D. Shemilt +2
In direct ink writing (DIW), neighbouring filaments of yield-stress inks are deposited side-by-side and are expected to merge into smooth, mechanically robust structures. Unlike Ne…

Air-driven dynamics of viscoplastic liquid layers
James D. Shemilt, Neil J. Balmforth, Duncan R. Hewitt
Airway clearance by coughing is a key mechanism for mucus transport, particularly in obstructive lung diseases associated with altered mucus rheology. We investigate the dynamics o…

Viscoplasticity can stabilise liquid collar motion on vertical cylinders
James D. Shemilt, Alice B. Thompson, Alex Horsley +2
Liquid films coating vertical cylinders can form annular liquid collars which translate downwards under gravity. We investigate the dynamics of a thin viscoplastic liquid film coat…
