Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

Superhydrophobic (SHPo) surfaces have been investigated vigorously since around 2000
due in large part to their unique potential for hydrodynamic frictional drag reduction without …

We review some fundamentals of turbulent drag reduction and the turbulent drag reduction
techniques using streamwise traveling waves of blowing/suction from the wall and wall …

Solar‐to‐thermal conversion is a direct and effective way to absorb sunlight for heat via the
rational design and control of photothermal materials. However, when exposed to water …

A number of well-resolved large-eddy simulations (LES) of a spatially evolving turbulent
boundary layer with uniform blowing or suction is performed in order to investigate the effect …

The mechanism of turbulent drag reduction (DR) with super-hydrophobic (SH) surfaces is
investigated by direct numerical simulation (DNS) and analysis of the governing equations …

1 J. Fluid Mech. (2020), vol. 894, A7. c The Author(s), 2020. Published by Cambridge University …

The occurrence of turbulent pulsations in straight pipes of noncircular cross-section leads to
the situation, when the average velocity field includes not only the longitudinal component …

While the global slippage of water past superhydrophobic surfaces has attracted wide
interest, the local distribution of slip still remains unclear. Using fluorescence correlation …

Turbulent skin-friction drag reduction with superhydrophobic (SH) longitudinal microgrooves
and riblets is investigated by direct numerical simulation (DNS), using lattice Boltzmann …
