Experimental investigation of passive cavitation control on a cylinder using proper orthogonal decomposition

open access: yesApplied Ocean Research
Cavitation is known for its hazardous effects such as material erosion, noise, vibration and drop in efficiency of hydro turbomachines. There are various approaches to control cavitation: surface roughness, cavity generator (CG), obstacles, and ...

Numerical Analysis of the Effects of Riblets on Drag Reduction of a Flat Plate

open access: yesJournal of Applied Fluid Mechanics, 2018
In recent years, marine transportation as well as land and air transportation has become in the centre of attention. There has been an attempt to reduce the drag exerted on vessels by various methods, such as rough surfaces and base bleed.

Higher-order homogenised riblet boundary conditions

open access: yes
The description of riblets and other drag-reducing devices has long used the concept of longitudinal and transverse protrusion heights, both as a means to predict the drag reduction itself and as equivalent boundary conditions to simplify numerical simulations by transferring the effect of riblets onto a flat virtual boundary.
