Blade Design with Passive Flow Control Technologies

open access: yes, 2020
This chapter focuses on the application of passive flow control technologies to wind turbine blades. The motivation of using these technologies is always an enhancement of the wind turbine performance (increase of power production, load reduction, noise reduction, etc.) in comparison to the standard blade.

The performance of passive flow monitors and phosphate accumulating passive samplers when exposed to pulses in external water flow rate and/or external phosphate concentrations

open access: yesEnvironmental Pollution, 2011
Passive samplers are typically calibrated under constant flow and concentration conditions. This study assessed whether concentration and/or flow pulses could be integrated using a phosphate passive sampler (P-sampler).

Passive control of backstep flow

Experimental Thermal and Fluid Science, 1998
Abstract The passive control of turbulent flow downstream of a backward-facing step using a permeable reattachment surface is described. An impermeable reattachment surface leads to the upstream convection of rotational fluid and pressure disturbances which is absent when a permeable surface is used.
