Linear models of strip-type roughness
D. Lasagna, G. Zampino, B. Ganapathisubramani
Prandtl's secondary flows of the second kind generated by laterally-varying roughness are studied using the linearised Reynolds-Averaged Navier-Stokes approach proposed in Zampino…
Aspect-ratio effect on the wake of a wall-mounted square cylinder immersed in a turbulent boundary layer
Gerardo Zampino, Marco Atzori, Elias Zea +2
The wake topology developing behind a wall-mounted square cylinder in a turbulent boundary layer has been investigated using a high-resolution large-eddy simulation (LES). The boun…
Scaling of secondary flows with surface parameters: a linear approach
Gerardo Zampino, Davide Lasagna, Bharathram Ganapathisubramani
Secondary flows are generated when a lateral variation of the topography, such as streamwise aligned ridges, is imposed to a turbulent wall-bounded flow. In this case, the flow fie…
Linearised Reynolds-Averaged predictions of secondary currents in turbulent channels with topographic heterogeneity
Gerardo Zampino, Davide Lasagna, Bharathram Ganapathisubramani
A rapid predictive tool based on the linearised Reynolds-averaged Navier-Stokes equations is proposed in this work to investigate secondary currents generated by streamwise-indepen…
