Sensing of minute airflow motions near walls using pappus-type nature-inspired sensors
Fig 3
Sketch of the wall-jet apparatus.
Air flow is generated with a planar nozzle flow that is tilted at an angle of β = 45° towards the bottom wall of the research facility and generates a wall-jet in direction of the sensor. The sensor is located at the centre of the bottom wall and the nozzle exit is at a distance of 20 slot heights H away. The 2D jet flow exiting the nozzle is pointing towards the sensor in x-direction.
