Effects of spatially localised pressure gradient histories on recovery of turbulent boundary layers
Zefanya Bramantasaputra, Dea Daniella Wangsawijaya, Bharathram Ganapathisubramani
Hot-wire anemometry is used to investigate the recovery of smooth-wall turbulent boundary layers from spatially localised (i.e. impulsive) pressure gradient history (PGH) effects.…

Characterisation of rough-wall drag in compressible turbulent boundary layers
Dea Daniella Wangsawijaya, Rio Baidya, Sven Scharnowski +2
In compressible turbulent boundary layers (TBLs), roughness drag is typically characterised by first applying a velocity transformation to account for compressibility, after which…

Effects of fetch length on turbulent boundary layer recovery past a step-change in surface roughness
Martina Formichetti, Dea D. Wangsawijaya, Sean Symon +1
Recent studies focusing on the response of turbulent boundary layers (TBL) to a step-change in roughness have provided insight into the scaling and characterisation of TBLs and the…
