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 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.…
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…
Investigation of unsteady secondary flows and large-scale turbulence in heterogeneous turbulent boundary layers
Dea Daniella Wangsawijaya, Nicholas Hutchins
Following the findings in \cite{wangsawijaya2020}, we re-examine the turbulent boundary layers developing over surfaces with spanwise heterogeneous roughness of various roughness w…
Time-averaged velocity and scalar fields of the flow surrounding a group of cylinders
Dea Daniella Wangsawijaya, Claudia Nicolai, Bharathram Ganapathisubramani
We examine the characteristics of mean flow and scalar concentration characteristics of a turbulent boundary layer flow impinging on a cluster of tall obstacles (which can also be…
