Generation and Breakdown of Surface Streaks in Wind-Driven Aqueous Flow
Asim Önder, Philip L. -F. Liu, Wu-ting Tsai
A bypass transition scenario in a wind-stress driven aqueous flow is analysed using a temporally developing boundary layer model with accelerating surface drift velocity. The param…

Stability of the solitary wave boundary layer subject to finite amplitude disturbances
Asim Önder, Philip Li-Fan Liu
The stability and transition in the bottom boundary layer under a solitary wave are analysed in the presence of finite amplitude disturbances. First, the receptivity of the boundar…
