摘要: Abstract Velocities of viscous fingers growing in a lifting Hele–Shaw cell are studied. The plates separated by pneumatic cylinder arrangement exerting constant force. It is observed that with air invading non-Newtonian oil-paint, finger velocities show an anomalous behaviour, rapid growth towards the end process. correlation coefficient between neighbouring shows dominant modes selected as pattern develops.
