Convection velocities and velocity coupling of outer-scaled wall-pressure fluctuations in canonical turbulent boundary layers
Rahul Deshpande, Abdelrahman Hassanein, Woutijn J. Baars
This study shows that the turbulent velocities most strongly correlated with outer-scaled (-scaled) wall-pressure fluctuations beneath a zero-pressure-gradient boundary layer r…
Instantaneous convective heat transfer at the wall: a depiction of turbulent boundary layer structures
Firoozeh Foroozan, Andrea Ianiro, Stefano Discetti +1
We demonstrate the ability to experimentally measure fluctuations of the convective heat transfer coefficient at the wall in a turbulent boundary layer. For this, we measure two-di…
Scaling of wall-pressure--velocity correlations in high Reynolds number turbulent pipe flow
Giulio Dacome, Lorenzo Lazzarini, Alessandro Talamelli +2
An experimental study was conducted in the CICLoPE long-pipe facility to investigate the correlation between wall-pressure and turbulent velocity fluctuations in the logarithmic re…
Measuring time-resolved heat transfer fluctuations on a heated-thin foil in a turbulent channel airflow
Antonio Cuéllar, Enrico Amico, Jacopo Serpieri +4
We present an experimental setup to perform time-resolved convective heat transfer measurements in a turbulent channel flow with air as the working fluid. We employ a heated thin f…
