IR thermography for dynamic detection of laminar-turbulent transition
TL;DR: In this article, the potential of infrared (IR) thermography for the dynamic detection of laminar-turbulent transition is investigated, and three different heating techniques are used to apply the required difference between fluid and structure temperature: a heated aluminum structure is used as an internal structure heating technique, a conductive paint acts as a surface bounded heater, while an IR heater serves as an external heating technique.

TL;DR: In this article, a single dielectric barrier discharge plasma actuator is employed for flow control on the pressure side of a natural laminar flow wing section under free-flight conditions.

Active flow control of laminar boundary layers for variable flow conditions
TL;DR: In this paper, the stability of a fxLMS controller for active wave cancellation of broad-band Tollmien-Schlichting disturbances in a flat plate boundary-layer with a single DBD plasma actuator is analyzed up to an unstable behavior.

Cancellation of Tollmien-Schlichting Waves in Direct Vicinity of a Plasma Actuator
TL;DR: The active cancellation of Tollmien-Schlichting waves is a promising and energy-efficient laminar flow control technology with the goal of drag reduction by delaying the Laminar-turbulent transition as mentioned in this paper.

TL;DR: In this article, a DBD plasma actuator is operated on the pressure side of the glove to delay natural laminar-turbulent transition while an infra red (IR) camera is mounted below the wing allowing a measurement of the spatial development of the transition.
