Work Package 1

 

WP1: Transition to Turbulence

Group lead:  Dr Sylvain Laizet

Members:   Prof Dimitris Drikakis, Prof Shuisheng He, Prof Neil Sandham, Prof Spencer Sherwin, Prof Paul Tucker

The Work Package focuses on mechanisms that cause laminar flows to become turbulent.  Transition to turbulence is ubiquitous and has profound implications, e.g. boundary layer transition to turbulence leads to significant increase in drag and heat transfer, particularly at high speeds.  Also, understanding the transition mechanisms can guide flow control strategies.
