Reynolds number effect on drag reduction via spanwise wall oscillation in turbulent boundary layers
The Physics of FluidsThe effect of Reynolds number on drag reduction via spanwise wall oscillation (SWO) is investigated through direct numerical simulations of flat plate turbulent boundary layers (TBLs) over a wide range of Reynolds numbers (i.e., 344≤Reθ≤2340).

Effective Underwater Drag Reduction: A Butterfly Wing Scale-Inspired Superhydrophobic Surface.
ACS Applied Materials and InterfacesThe microstructured superhydrophobic surface serves as an alternative strategy to decrease resistance of underwater vehicles, but the sustainment of an entrapped air layer and the stability of the corresponding gas-liquid interface within textures in ...

Nanoscale Drag Reduction Effect Enables Efficient Fog Harvesting
Advanced Functional MaterialsSurfaces with macro‐scale hydrophilic/hydrophobic regions (conventional Janus mode) are often considered as prime candidates for fog harvesting. However, the water collection efficiency of such surfaces frequently fails to meet the requirements of ...

Analysis of drag reduction and partial setup of riblets surface on the airfoil
The Physics of FluidsUsing riblet structures to modulate the turbulent boundary layer to reduce frictional drag is important for vehicle stability and range. The flow on the airfoil surface at different angles of attack is different, and the effect of the riblets structure ...

Biomimetics
With the aiming of solving problems with the existing ordinary excavator buckets used in the process of operations (such as heavy digging resistance, ease of adhesion, and others), seven types of bionic buckets and a prototype bucket were designed, based
