DEVELOPMENT OF SECONDARY CROSSFLOW INSTABILITY NEAR BREAKDOWN INTO TURBULENCE
E. van Bokhorst¹, C. Atkin¹; ¹University of London, United Kingdom
Transition from laminar to turbulent flow on a swept wing with a favourable pressure gradient is dominated by crossflow instability. The ultimate transition mechanism is a high frequency, secondary travelling mode which grows explosively after which the flow breaks down into turbulence. This paper presents an experimental visualisation of the later stages of this growth.
