Optimization of Drag Reducing Shark Inspired Blade-Shape Riblet Surfaces in External Flow

Journal of Applied Fluid Mechanics, 2020
The main goal of this research is to study the drag reduction capabilities of blade-shape riblet surfaces in external flows. For this purpose, the ability of riblet surfaces for drag reduction of an underwater hydrodynamic model has been investigated ...

Stability of the flow over superhydrophobic micro roughnesses: The influence of the interface

International Journal of Thermofluids
Superhydrophobic surfaces are known for their drag reduction properties. However, the interface between the lubricant and the overlying flow may easily become unstable, leading to the depletion of the superhydrophobic layer and to a consequent drag ...

Review of Passive Flow Control Methods for Compressor Linear Cascades

Applied Sciences
This paper reviews the evolution of flow control methods for bladed linear cascades, focusing on passive techniques like riblets, grooves, vortex generators (VGs), and blade slots, which have proven effective in reducing drag, suppressing flow separation,
